> it's amazing to me how gullible everyone was

I have some bad news for you.

Claimed UFOs sightings seem to have become less common since everyone is expected to carry a digital camera with them all the time (in their phones). Similar for Loch Ness etc.

But it's not like people don't like their outlandish theories anymore. Alas, they've become very politicised, too.

To give an example that's hopefully not too polarising: many people like to blame inflation on greed.

>Belief in aliens and UFOs was popular in the 1970's. Looking back on it now, it's amazing to me how gullible everyone was. Maybe it was the high lead content in everything...

There's no shortage of people today who still believe in various religions.
