Well, thanks for proving me wrong. I thought that I was wrong. But since you have proven me wrong, I am right.
Two major reason why Evolution has not been proven true are:
1. Nobody can track the DNA of plants or animals over the many thousands of years it would take to see if even one of them changed into another, and probably, nobody will ever be able to;
2. We can date pottery back to between 4500 and 5000 years. But back beyond that we don't know for a fact that the methods we use are the methods that will work on things back then. Math, itself, might have been different back beyond 5000 years, as might have been the physics of the universe. Everything we use as proof might have acted differently back then. We simply don't know.
When we don't know, and know that we don't know, yet say that we do know, that's when the hoax comes into being.
Evolution is a hoax.
You forgot to add:
3. Nobody can time travel therefore anything that happened in the past cannot be proven ever (unless it's the claim that god existed and performed miracles in which case, yes, it can somehow be proven)
2. How would math be different 20.000 years ago, you are just talking nonsense, if that's your argument, then everything could have been different at any given time, then we might as well just give up.
Well, well, well. You are starting to get the picture a little. Since we don't know how math and physics might be different a little, or the same for that matter, we obviously don't know that the earth or universe are billions of years old, or that they are even 20,000 years old.
Since we know that we don't know these things, yet we proclaim that we know these things that we know we don't know...
Evolution is a hoax... and you agreed.
