>>897If there was extraterrestrial intelligence on nearby planets within our solar system, we would've seen them by now.
We sent probes to Venus and Mars for five decades now.
We mapped the surface of Venus with radar, infrared, and ultraviolet.
On Mars, we have rovers that test the soil for any microbes.
We still haven't gotten any results back where there are any sentient beings on the surface.
If there is extraterrestrial life within our solar system, chances are they could be microbial.
