Im regards to Mars we have very little idea what is going on there. There is serious paper proposing fungi like life has already been observed but we haven’t recognized it. My understanding is a significant number of serious astro biologists think it’s likely there is currently life on Mars. I’m definitely unaware of any archeological digs on Mars. Since we are on the fringe topics I’ll mention that another related thought experiment is assume an advanced earlier Mars or Earth civilization moved to the Saturn system and currently resides there leveraging its abundant resources. Would we have actually detected it already?
