- Meteorite samples from an ancient impact site situated in Germany, hint towards the possibility that oceans and life existed on Mars.
- According to a recent study done on the meteorite samples of the RiesCrater, formed roughly 15 million years ago, Mars may have been warm enough to surface oceans and life.
- Though it is unlikely that Mars would have had enough oxygen to support complex life structures like humans and animals, simpler microorganisms could have possibly sustained themselves if Mars had water with a neutral pH level and was highly alkaline.
