> There is likely simple basic life as advanced as bacteria around the universe

What is the basis for this assertion?

single-cell "life" can be so simple that scientists can create it in a lab "SpudCell"

somewhere among 2 TRILLION planets in our galaxy there is a planet with enough atmosphere and magnetosphere to protect it from space radiation so there is likely bacteria

but complex life far more difficult and unlikely, very rare, as explained in the PBS Space Time I linked above, the "Cambrian Explosion"

if there are viruses and fungi out there however, they could mutate eventually with enough permutations and outside stressors
