Last Thursdayism (alternately Last Tuesdayism or Last Wednesdayism) is the idea that the universe was created last Thursday, but with the physical appearance of being billions of years old. Under Last Thursdayism, books, fossils, light already on the way from distant stars, and literally everything (including your memories of the time before last Thursday) were all formed at the time of creation (last Thursday) in a state such that they appear much older.This theory is used by certain creationists to explain how the Earth is only 6000 years old. They claim that the universe was spontaneously created 6000 years ago.
I am a Young Earth Creationist. And I've never heard any creationist espouse that. What I teach is that everything indeed was created roughly 6000 years ago. The one exception that you seem to be hinting at is where did the starlight come from?
Well, some creationists try to claim that the stars are all accelerating away from us but were originally very near to us. This is a scientific fallacy, though as the gravitational forces involved would have ripped apart the earth. Before realizing this problem, I considered the idea to be a possibility, though I never really espoused it, myself. So, I try to discourage other Creationists from using this "proof".
The best reason for existing starlight is much simpler in my mind. This spoiler includes basic science from Genesis chapter one.

I don't believe God created the light en route. But I do believe he created the scientific laws that allow energy to be transmitted as light. That is the light created on Day one of creation ("Let there be light"). To me, that was the creation of energy and darkness was the matter. In other words, on the first day of existence, God created all matter as a blank slate and then added energy (i.e., electrons). This is also why photons follow the Biblical principles of light and darkness. The Bible treats darkness as a place and light is what fills a place.Day four of creation was when God "lit the furnace" so to speak of the stars and radiated energy was allowed to be emitted. Thus the sun and stars shown while the planets and moon reflected that light. Day three saw the creation of vegetation but they couldn't have survived without the creation of the sun on day four to emit the light needed for photosynthesis.
So, there is light and darkness. Matter was created first, followed by energy. The earth was then specifically formed and then filled with vegetation. Then the stellar bodies were created. This is in direct opposition of the evolutionary concepts of the order of creation. This also helps to disprove the evolutionists who try to mix evolution and the Bible.
But here's the part about why starlight reaches us from so far away:

The concept that the speed of light as a constant is mathematically incorrect. It is based on poor assumptions about the nature of gravity in relation to light. The notions taught about black holes hint at the truth, but -- unfortunately -- fail to help people make the leap of understanding to realize that light speed is actually variable. Black holes do hint at the causality. The conceptualization of the lack of visible spectral light is based on it not escaping a black hole due to the immense gravity. The point is that the gravity is so strong that the light cannot escape its grasp.
Again, some scientists kinda get close to understanding this principle when they deal with the lensing affect that a stellar mass has on light waves that actually travel around their edges. This is a theory widely accepted by astronomers. Then there also is the concept of wave lengthening that occurs with the Doppler effect -- another theory widely accepted by astronomers.
In the case of the Doppler effect, a light wave will actually increase its period between wave crests, creating a "red-shift" in the visible light. This is determined to actually slow down the radiative wave such that light speed has already been proven not to be constant even within the entire spectrum (x-rays are already known and proven to travel faster than the speed of visible light...which is a part of why x-rays can escape black holes while visible light cannot).
Now, when you realize that light speed can travel at different speeds, it is therefore acceptable to anticipate that the speed of radiation is variable even for specific wavelengths. The determining factor occurs in relation to a gravity source.
Already it is known that time is perceived to travel faster away from a gravity source. Clocks on satellites in space have to be adjusted to run slower to account for this. Without a full understanding of this concept, GPS satellite data would be useless to us on earth.
The same is logically true of the speed of light. If the force of gravity can affect visible light via black holes, lensing, and the Doppler effect (which some might volunteer as not being gravity related, rather an effect of long-term light-wave degradation...but there is no reasonable basis for this), then it is reasonable and actually logical to assume that the force of gravity affects the speed of light.
The hypothesis that I espouse -- which uses mathematical principles that better fits the formulas of the General Theory of Relativity than the commonly-accepted alternative math using light speed as a constant -- suggests that the further away from the pull of gravity that a photonic wave of radiation gets, the faster it travels...much faster.
Therefore, according to my hypothesis, when a star shines, the speed of light goes fairly fast away from the star -- toward us, for example. As that light leaves its originating solar system, it continually accelerates...bending its path to and fro as affected by other stellar objects. Eventually it reaches a zenith of speed that occurs at some point roughly midway between us and its origination.
Then, after that zenith point (not necessarily the midpoint because the source gravitational pull is likely not equal to the destination gravitational pull), the light actually begins to decelerate as it approaches the gravity source at the photonic wave's ultimate destination.
So, by this concept, the light speed of photonic wave radiative light that reaches us from distant galaxies may have only just left there a mere few years ago...or decades perhaps...or maybe just months...or weeks.
The reason why this is not a well understood concept is that -- when measuring the speed of light in our own solar system, the numbers are based on very short distances. The speed of light is determined for a meter of distance. Thus a light-meter is then converted to light year and it's based on a relatively short measuring distance used to determine the light speed.
Now, if we were able to measure the speed of light over a short distance and then compare it to a specific measurement across a much longer distance, then the variable speed of light ought to be able to be detected. However, since that would be the final nail in the coffin of uniformitarianism, I believe that most astronomers and physicists would refuse to accept any proof of this (fanaticism among evolutionists is stronger than ISIS in many cases).
The scientific principles that justify this theory are far too complex to include here, but I can point anyone who wants to research this further to some good reading materials that treat this subject with good research and objectivity. Just pm me to learn more.
I hope this isn't too technical. But don't reply with the useless statement of "TL
R" ... as I've included the details within a spoiler. If you can't handle a little reading, then don't bother to participate in the discussion. If you can't take the heat, stay out of the kitchen.

It seemed like such a waste to destroy an entire battle station just to eliminate one man. But Charlie knew that it was the only way to ensure the absolute and total destruction of Quasi-duck, once and for all.
