I do believe that there are things that will not be explained or discovered within my lifetime. And I have witnessed and experienced the 'paranormal'. Most people have, 'Deja Vu' for example has no explanation; and yet you'd find it difficult to find a person that hadn't experienced it.

But at the same time, science is constantly evolving and adapting; science is not a static concept. 15 years ago; pluto was a Planet, now it's a dwarf planet. 10 years ago the consensus was that Neanderthals died out; now the growing consensus is that they assimilated with homo sapiens. And these changes are happening at a faster rate. So hopefully science picks up on this and answers these questions.
