Not all life will prevail from the looks of it there on Mars and here on Earth, and the Drake equation argument is something to consider as well. With the expanding universe 'grabby' and 'quiet' aliens will most likely never reach their intergalactic travel goals.
"Almost all arguments involving the Drake equation suffer from the overconfidence effect, a common error of probabilistic reasoning about low-probability events, by guessing specific numbers for likelihoods of events whose mechanism is not understood, such as the likelihood of abiogenesis on an Earth-like planet, with estimates varying over many hundreds of orders of magnitude. An analysis that takes into account some of the uncertainty associated with this lack of understanding has been carried out by Anders Sandberg, Eric Drexler and Toby Ord,[46] and suggests "a substantial ex ante probability of there being no other intelligent life in our observable universe"."
