no such thing as aliens YET******
There is no way they can travel at the speed of lightl.
Maby their build diffrent compared to human.
But what we see as living, means it eats sleeps and it can take a shit.
We cannot travel at the speed of light, becouse the fact we're to soft. we cant handel the force.
Also, Nothing availeble on planet earth can give us such an ammount of acceleration.
And also, There are millions of stars, but all so far away.
So many galaxies, but so far away
So many planets, but so far away.
Get my point?
And piramides, Meh all bullshit, we were smart enough back those days.
how else did we accomplish to kill a mammoth when we were still a retarded bunch of monkeys jumping around with a stone in their hand.
After a while, they realized that they could use the bones of the dead animal, sharpen them, and cut things with it.
