Are there any credible scientists that believe in UFOs (alien ships visiting earth)?
I recall Michio Kaku was very open to the prospect but he could be saying it to boost his celebrity (who knows).
I would imagine that while there are likely no civilisations within our radio bubble that ships or probes may have detected them but then again we’ve only been pumping them out for ~100 years which is not even a blip in time.
