Do you think aliens in ufos have visited Earth? (And all things UFO)

I've been following this pretty closely for a long time.

I would be wary of any video that doesn't have serious chain of custody that points to a source that isn't interested in the UFO topic.

I've seen so many videos over the years, and even sent a couple of friends because i was sure they were real, only to have them either be clearly explained as something else or just plain fake.

The growing public interest could be completely demolished if a video comes out that people buy into and it turned out to be fake. People would just stop paying attention, and the Congress would just stop digging.
