Question: what would life be on mars

Helloooo! Interesting question. Mars probably at some point in its history had oceans and seas, and so had a environment much more likely to support life. If life evolved there, I reckon it would be similar to us, so carbon-based, but would probably be able to deal with the lower gravity, and would have to deal with much colder temperatures. If it did evolve, it didn’t have a huge amount of time to evolve into something really complex, because Mars is smaller that the Earth, it lost its magnetic field quite early on, which left the surface vulnerable to solar wind, which basically boiled off the oceans and seas. If life had to survive it would probably have had to go underground at that point. Unfortunately we haven’t found any evidence of Martian life, past or present, with any of the rovers that are currently on the Martian surface, but we’ve only covered a small part and lots of future missions are heading there. So who knows!

On another note, if humans decided to move to Mars, life would be pretty rough I think. Its cold, there’s lower gravity, we can’t breathe the atmosphere. We’d have to live in habitats where we change the air to something we can breathe! But there is some frozen water at the poles, so we could get water from there, and the gravity isn’t SO low that we would suffer from bone density issues, like astronauts do on the ISS. Also another big thing on Mars, the day is roughly the same as Earths, so we wouldn’t need to adjust our circadian rhythyms much, might not sound like a big deal, but imagine a nearly 6000 hour day on Venus! Despite that I def wouldnt want to live on Mars, I think Earth does a pretty good job.
