First: You are not the arbiter of what "real" evidence is. You have arbitrarily decided that the evidence is not real by virtue of the appeal to authority fallacy. that is, by it's very nature, illogical.
Second: There is plenty of real evidence to warrant further investigation into the hypothesis (and not just from the television program. The comments from the government officials are actually plenty to warrant further investigation in and of themselves).
There isn't enough data to make any claim in either direction. One can lean in one direction, but you are actively rejecting the hypothesis in the absence of any investigation. That's terrible science and logic.
Also, your attempts to claim that this is similar to truthers, UFOs and birthers displays a distinct inability to recognize the important difference between an absence of evidence (which leads to fallacious reasoning) and evidence of absence (which does not).
There is evidence of absence in certain cases, which leads to a tentative rejection of hypothesis and acceptance of the null.
There is no evidence of absence in this case.
