“Not just 100 percent proof of aliens, but proof that aliens rely on religion.”
But scientists have never found any evidence of life on Mars and it is unlikely they ever will.
If life ever existed on the planet billions of years ago, it would have only been simple and microbial.
NASA said: “Even if there were no life on Mars, it would be exciting to know whether there used to be life there.
“So in addition to looking for living bacteria, NASA will be searching for tiny fossils that might indicate life got a start early in Mars’ history but, unlike on our home planet, it did not survive and evolve into larger life forms.”
