I Am Forced To Believe In Aliens / ETs

You're committing a very common logical fallacy.

"I can't understand how it was done, therefore it couldn't be done."

Ancient people weren't stupid. They had engineers, scientists, astronomers, even doctors. They were smart enough to measure and cut stones. They were smart enough to create blueprints for monuments. You don't need computers do that stuff. Computers are just the tools we have chosen to use.

1) Easter Island - they rolled them. There are videos of people doing it online.
2) Simple geometry. We've known about it for a very long time.
3) They didn't. First of all, that's not the age of the universe. Second, they never said it was. Third, everything else you claimed is a load of crap.

You appear to be very gullible, like most people who believe in aliens visiting Earth. While there's a very good chance life is out there somewhere, there's no evidence it's been here. The distances involved are quite literally astronomical.

Apollo 18 found aliens on the moon....they happen to be moon rock that turn into a spider like creature.

Chariots of the Gods, man. They're falling out of the sky.........

There have been all kinds of scientists that have investigated the Easter Island statues, the pyramids, the Mayan culture, and other things.

If you want to believe uninformed or inaccurate sources, that's of course your choice. I won't waste your time or mine trying to educate you on the facts that you seem to have missed.

You are right, there are countless galaxies and worlds - and the possibility of life on other worlds is very real.

But that does NOT mean that aliens have visited Earth. Questionable "interpretations" of carved stone tablets (the Mayans didn't leave any documents, by the way) don't count as evidence.
