Really? An "electrical arc crater"??? What an interesting idea, and here I thought you came up with that hypothesis yourself.
Sorry to burst your self-imposed bubble of disinformation, but there is evidence that liquid water once flowed across the surface of Mars, and that Valles Marineris was probably cut by water...just like the Grand Canyon.
But please, continue to champion the oddball hypotheses. Your arguments are at the very least diverting.
As an engineer, I find tinfoil hats far more plausible than "electrical arc craters".
