First ever animal that can survive without oxygen

[Catherine]

Quote: So life on other worlds could well be possible, without the need for all four elements to all be present.

Life elsewhere could exist with out any of the four elements. Who knows what is possible.
At one point they assumed the earth was flat. We need to stop assuming and be more to possibilities.
Who knows what life might exist at the very deepest part of the ocean. It would have to be very different from any life that we know now.

The possibilities are endless.
