Where are the physical traces?

Since this forum mostly presents videos for discussion, are there other forums where supposed physical artifacts are discussed? (Something other than plaster-looking mummies, that is)

In an earlier post, i bound up several questions, and it became a mish mash of discussion. Now i am focusing on one issue.

I’m wondering where is the stuff left behind, in addition to sights and sounds recorded on videos.

Lue Elizondo has said there are physical traces that the government collects. Gary Nolan looks into these kinds of things, so there is some physical evidence being analyzed.

It seems to me with all the ongoing, contemporary sightings, there should be some physical evidence in the hands of regular people, too.

There are plenty of historic cases with say, imprints of a heavy object left behind. People received radiation burns, or areas on the ground no longer allow any plant growth. Then there are famous crash events like Roswell where debris is allegedly found.

Don’t any of you have stuff you can show us and tell us about? Again, not just videos, but physical traces that accompany the weirdness. Or maybe you don’t have videos of flying discs, but maybe you have glowing goo or some weird metal.

Should I visit other forums where this kind of evidence is presented and discussed?
