Is panspermia even more mainstream that I thought? The new (potential) traces of early life were used in none other than space.com to tout the possibility of panspermia: http://www.space.com/scienceastronomy/lava_life_040422.html Here's the quote: "Nobody knows how life began. Scientists aren't even sure if it started on Earth first or was transported here by Mars rocks or in the bellies of comets. They do know that Earth was initially inhospitable and probably dry as a bone when it formed about 4.5 billion years ago." Anybody else seen panspermia rising to the forefront as an explanation for the origin of life?
