Day to Day happenings in my life

Alien life.

PROMPT March 9th

Write about the mythical or science fiction creatures/beings that could actually exist. Imagine a world where there was definitive proof of their existence - how would life be different?

I steer clear of any story which has an alien being as it’s MC. So therefore I’m ill equipped to write about such beings.
However after the trouble the covid 19 organism caused, I could be convinced an invasion from another planet is possible. The being doesn’t need to be massive, ferocious and with large teeth, ready to destroy anyone unfortunate enough to get in its way. No I believe the invaders will be microscopic, they are much more to be feared. We can’t see them or hear or touch them. Their infiltration will be silent and stealthy.
