Is It Possible That on Mars There Are Lava Caves?

In 19 96, a group of scientists found a structure within a rock that had come from mars. But it still doesn't add up to that fossil being coming from mars. It's going to be very difficult. Ou'd better not look for microbes and li up the game and look for sea monkeys or some well, you know, we've got all these infinite monkeys that are kept in a cagean goodness knows whether any of them have ever been to mars. I think if there was anything higher, more evolved on mars, like mere cats or something like that, they would have been seen.
