Isn't Mars just a cold barren wasteland?
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 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?
