I think it's unfair that we can't time travel.

I'd like to see how the world, at least earth was created, how the human race evolved, what will happen to humanity a billion years from now etc
I'd like to know for sure, I'd like to be certain. Not some scientific theories.
It's frustrating for humanity to have brains and be this limited! It's the lack of knowledge that creates the religious cacophony, pseudoscience, racism and all scourges of this earth.
