Isn't Mars just a cold barren wasteland?
Why did they invent logboats and sailing boats in those days, why not just focus on nuclear powered carriers?
hy not just focus on Wormholes until you can finally Kepler 22b or whatever
Because Mars exists
Consider it a second chance at Earth. If things get even worse here
Planet is red.
Red because of rust.
Scratch surface, its all light grey underneath red rust.
Scientists say atmosphere in Mars has trace elements of some kind of nuclear element or something only found after nukes.
Basically this means the planet was glassed a millenia ago.
The question is how does a planet glass itself to the extent its just rust. Not probable.
So ... basically.......what im saying is
So i propose the great filter is basically the covenant glassing a planet once something happens.
Now the question I have is what is the signal?
