What do you guys think? Aliens or no aliens?
I'm kinda inclined to believe that given how large the universe is and how on so many occasions people have seen weird shit in the sky, that there might actually be such a thing.
Additionally, those ancient structure especially some of the ones in mexico are too perfect and too immense to have been made by people in the stone age. We can't even replicate those structure today in the 21st century with the same accuracy let alone explain how these ancient people were able to it.
Definitely some buzzy shit...

"The stone structures in Puma Punku are made up of granite, and
diorite. Interesting enough, the only other stone that is harder that those
two is the diamond. If the people who built this place cut these stones using
stone cutting techniques, then they would had to have used diamond tools"
