David Icke, for me, is very good at spinning a yarn, but falls somewhat short of any revelations and ends up with more questions, rather than answers.
I am more inclined to believe that military aircraft are responsible for most sightings of UFOs or UPAs. Just because we have a large number of amateur astronomers who have never witnessed vehicles from another planet flying towards earth.
Like Icke, I do wonder to what end the US military publicising 'UPA events' is heading towards. I would think a large number of the population are very sceptical (like myself) of visiting alien life, and it would take something huge to change that opinion, not just testimony and vagueness from ex-pilots.
Covid was a much easier way to get public compliance, than concocting aliens.

a related point for those who think this all credulous madness - Francis Crick, co-discover of the DNA helix, was a materialist and atheist who thought the universe was all matter and energy and nothing else, but he did not believe that DNA could ever emerge out of inorganic chemicals, and cell membranes are another unsolvable problem, he thought it more likely that viral and bacterial material passed through space - and Sir Fred Hoyle, another giant of science and architect of the field of bio-chemistry also though the emergence of DNA by random was impossible (the odds he quoted of it happening were a google to one!). Hoyle speculated that this viral material would be carried by comets, and lo and behold he was proved right (billions of tons of this stuff have been found in comets). Hoyle maintained that microbial life was found on Mars by Viking. Crick did not go with the comet theory but speculated, more plausibly to himself, that 'panspermia' originated from alien civilisations sending out viral and microbial material. So it's not all Twilight Zone - you can't answer certain questions without resorting to God or aliens, even if you're a confirmed atheist like these two were.

You know you've seen a black and white picture with metrics you don't understand and saying its aliens.

Your sentence is usually "I don't know what that UFO is therefore it must be aliens".

Your sentence should be "I don't know what that is" and ends there. If you don't know what it is, how is your conclusion aliens?

I'm not saying I don't believe in aliens its just that there needs to be good evidence before you can say so.

There's a great line in a book called 'Do You Believe in the Afterlife?", where a question is asked whether the recipient believes we are the only life in the Universe. You never hear the reply but the follow up question is: "So do you think we are the start of life in the Universe or the end of it?" Are we the first forms of life or has all life retreated to this Earth and it is the last bastion of living things. We could be alone but there are so many other galaxies that would suggest that somebody somewhere should be advanced enough to visit us.

hats off to palace, they were always gonna be louder, and hate to say it but they were impressive ALL bouncing and singing.

Again, you are making assumptions.

One, that NASA, NORAD or any other defence system doesn't actually see them and keeps it a secret, or that the aliens would allow us to.

In the end, people want physical evidence. They want the alien body or the crashed spacecraft. They are unlikely to get either any time soon. Even if they do, many still wouldn't believe it.

I personally think we are in the process of a slow disclosure.

Governments could have been lying to us for decades over this.
They will most likely engage in a little charade to avoid acknowledging that. There could also be very important national security reasons why the whole truth must be obscured.
Worst of all, governments might have done things involving ETs that the public could not stomach. After all, they killed the Kennedys and a host of others, and they will never own up to that. Of that I'm very confident.

All stuff involving aliens is guess just work of course. Without the facts, that's all any of us have.

If an unelected body within government stops at nothing to keep all such things secret, what sort of evidence would you expect to find?

There is plenty of testimony from credible people which would be believed by a court if it involved just about anything else.

Among all the misdirection and daft stuff, there is enough here to indicate that something is going on.
