Life is universal?
Here is a wacky idea: life is universal.
What is life? Self propagate, with boundary, and affect environment.
Computer "virus" is a real life form, not a metaphor.
The Sun has CME, a massive EM waves generator; the Earth has a iron core, actually probably most planets have metal cores. Wherever there is metal, there's EM energy.
Astronomical in number, massive, billions of years. The probability of NOT having EM life form is small.
EM life form doesn't need to be binary, it can be ternary, hex, octal, or most likely, analog.
