This is unfortunate

This article seems to suggest that the prospects for early life on Mars were not very good.

Then again, Earth apparently suffered a similarly heavy bombardment in its very early history, and life evolved nonetheless. There have been suggestions, from Paul Davies and others, that life actually evolved not on the exterior of planets (prone to cataclysmic events such as the above) but in the safe, warm, stable interiors. Which indicates that there might be Martian life today.

(To say nothing about life in the interior water oceans of Europa, Callisto, and Ganymede, or in Venus' upper atmosphere, or in selected niches on Titan, et cetera.)
