Yeah, that's true. And Earth X is technically a different continuity from 616, even if some concepts from Earth X have been incorporated into 616, so whatever applies to Earth X doesn't necessarily have to square with 616 canon. As for Aaron's take on the origin of life on Earth in the Marvel Universe, I thought that was so utterly nihilistic, but then Steve's answer gave me new life, paraphrasing from DC's Blackest Night, which also posited that life in the universe was an accident and/or an aberration --- "Life doesn't give us purpose. We give life purpose." Right on, Captain.
