There once was a freshwater lake on Mars that had the ability to sustain life. A report from NASA states that the Curiosity Rover has discovered “Yellowknife Bay” on Mars once had conditions very similar to those on Earth and had the ability to sustain life.
They did not find any evidence of life itself, but this is a huge leap forward in terms of finding evidence that alien life was indeed possible and likely. A previous finding from NASA revealed that Mars was once possibly suited for life, but this new report goes further in stating that life could have been sustained as well.
We will keep you updated when (because it is only a matter of time at this point) they find the first evidence of alien life. Until then, stay tuned!
