I'll apologize for my assumption that you were arguing about the existance of alien craft, but then have to ask, what is your point in making the "argument" that people have spotted things in the sky, and they didn't know what they were? That's like making the "argument" that some people eat breakfast, or that some people prefer red cars.

The fact that people see something in the sky, and cannot immediately identify it means nothing more than...well, that they saw something in the sky that they couldn't identify.

Additionally, the fact that people then investigated the fact that someone saw something, and were unable to determine what said person/persons saw, means...well, that they didn't have enough evidence to make an identification of what was seen.

So now that we're in agreement that things have been seen and people did not identify them...so then what's your point?
