Mars Might Have Been as Hospitable as Mars Was a Long Time Ago?

There's an excellent chance that will that question. And i think there's a good chance that the answer will be that it was hospitable. But if it wasn't, that's of course, really, really important for us to know. Recent models that have been done using general circulation models,. The same kind of models we used to predict climate change on earth. They point towards thinking that venus may have been habitable for a long time. When i say recently, i mean one or two billion years ago, which is recent. There cold have been life evolving on venus. There could have even been exchange of material between the two planets, carrying living organisms. Who knows.
