I watched a video that said it would take 5 years traveling at the speed of light to reach the nearest star to our solar system. And 100,000 years at the speed of light to be able to see the milky way galaxy in its entirety. So does this mean that everything scientists look at in space are an image (reflection of light) from hundreds or thousands of years ago? By the way, when people say "light year" is this just a measure of the distance traveled by light in a year?

I personally believe in evolution. There is no proof of intelligent design. None at all. However, there is proof of evolution. Also the intelligent design main idea is that something created the world right? There is an obscure religion that believes the same exact thing but replace the word "god" with "aliens".


Oh, and don't say I'm going to hell and not heaven or whatever. Theres no proof they exist either.
