"Imagine if we found evidence of past life on Mars or Europa."
In the past, one could imagine. But there are Mars orbiters returning Google Earth quality images of the entire planet. Here's the Curiosity rover seen from Mars orbit.[1] If there was anything living on Mars as big as a patch of lichen, it would have been found by now.

This statement is ridiculous. Evidence of life on Earth millions of years ago is buried deep in the Earth soil. Mars exploration has literally only scratched the surface of the planet, a few inches deep.
