Obviously...

We went to the park this morning. While there we saw a military plane fly by overhead, fairly low as if about to land. I said, there must be a UFO nearby, because that is what the military does most of the time you know. Then a short time later we saw a military helicopter fly by also sort of low. I said, see, that helicopter is also headed to the UFO site. Plus if we don't hear about it on the news then that means it was definitely a UFO, you know, because of the cover up. In fact there might even be a story about something completely different and that will pretty much guarantee that it's a UFO.

So we went to the park and did not see a UFO but I'm still pretty convinced that it was there.
