Skepticism is normal and understandable but I'm surprised at the amount of uninformed skepticism on this topic here. It seems like a lot of people still don't know what's going on.
So many credible, high-ranking people in military and government have come forward over the years. Edgar Mitchell had a PHD and walked on the moon and tried to tell us about UFOs.
Aliens are exciting so people want to believe. It’s boring to conclude that your brain spazzed out and you saw something that wasn’t real. Or that you saw some strange looking natural phenomena that you don’t understand. But this happens all the time. Not to mention hallucinations, altered mental stages, optical illusions, exotic atmospheric phenomena, and so on...
I would need the most compelling evidence humanly imaginable to seriously consider the idea.
If these are hyper-intelligent beings, I would imagine they made some sort of digital clone of themselves so they could explore space without carrying around a biological body through space which would die faster than a digital clone. With a robotic digital self you could live for millions of years exploring, and then when ready, bring lots of data back home from your travels and recon of other planets.
