What are your thoughs about this? Are there really aliens visiting our Earth or is the US working on some (classified) projects?

I also want to ask this question, which has bothered me for a few days now:

Why does so many Alien vessels crash on our planet? Are it those TV and radiosignals of us who disturb the (sensitive) equipment in their vessels?

I think that it is most likely the US government working on some projects, but who knows?

The Truth Is Out There...
