i asked a brilliant question earlier about mars and they kept telling me that you cant grow a tree in ‘rust‘? whatever, rust comes from metal, right? so that means there is metal on mars? and isnt metal man made? come on people be smart! duh! of course there was/is life on earth!
I doubt the brilliance of your previous question if you could get this one that wrong. Rust doesn't come from metal, metal, (basically), is refined from rust.
Rust comes from iron. Iron is found naturally on Mars.
Iron oxide on Mars isn't from metal it is from iron rich ore in the soil.
