I was just going to ask what they think happened to the water. Your theory makes a great deal of sense.

I know I’ve read that somehow Mars’ gravity wasn’t enough to keep its atmosphere and under that I guess the water would have sublimated off into space. Seems contrary to the ocean being there in the first place though.
