UFOs are 1) Secret Goverment Technology made and controlled by elites. or 2) . Supernatural beings, often demonic ones. or 3). atmospheric weirdness, birds, halluctinations, etc. Easily explainable by other means, no ufos needed.

If you think the common man is going to have such tech before our "Betters" allow us to, i have a quantum portal to sell you.

There is no reason to assume there is sentient life on other planets. Real technological UFOs are made by MAN and or demons.
