Wolfgang, I am better impressed by the personal accounts I have heard from highly qualified witnesses than I am by your apparent emotional desire to somehow discount them or explain them away because they aren't in accord with your chosen world view.

Of COURSE, I can't know for certain. ;-) I never said I could. I am merely assessing what seems most probable to me, given my own experiences, and the personal accounts of many others I have met. I have said in the past that there may be other explanations than that we are being visited by advanced alien lifeforms. There may indeed. People might, for example, have seen secret vehicles built by our own governments. But I think it is more probable that we are being visited by advanced alien lifeforms.

I am not declaring certainties. I am theorizing as to what seems most probable to me.

Wesley - Yes, I'm sure there are many doubters who, like you, wish it were so and there were alien visitors. ;-) They don't make such pests of themselves, though, as the professional debunkers who are determined to attack any witness who thinks it may be so...those debunkers seem bent on attack and ridicule and specious stories about weather balloons or "swap gas" rather than on having a fair and balanced discussion, and I frankly suspect that some of them are in the employ of certain government agencies who are managing a very large coverup. If so, it isn't just the US government that's involved. It's all the major governments.
