there are other groups that speculate about Tera-forming other worlds for human habitation. Before proceeding with Tera-forming we should be mindful of the possible multitudes of extreme life hidden in the cracks, crevices, and depths of those worlds.
A common theory that life on earth, and therefore may be common on other planets also, received a 'jump start' when a 'soup' of chemicals was energized by lightning. The 'recipe theory of life' maybe missing a key secret ingredient. That ingredient necessary to bring the broth of life to life, could be the intense pressure of the deep. Many other worlds possess the necessary ingredients and would be good candidates for life in the deep.
Therefore there is something new, disconnected from the sun, under the sun ... and probably under many other suns.
