We aren't talking about chemical reaction here, we are talking about mining gold and that's a huge difference.

Let's recap this again. These aliens who are millions of light years away (otherwise we would've found them), came to our planet. They then mated with an ape and changed the DNA code by only 4 percent (human and chimp share 96% same DNA strands) so that they can start mining golds. They will then hide somewhere and "steal" our gold coz they were not developed enough to bring a super machine that would simply extract all the earth's gold.

I admired your comparison of creating water. A better one would have been genetically modifying a bee to produce sweeter honey. But the big difference, again, is the fact that mining a gold is not a big deal. Tell me, if you were an Alien would you mate with an ape to create a human and then wait for hundreds of years before human being actually started mining golds or simply create a machine that can do the work for you instantly?

My whole point about conspiracy theory is that they present legit (and often illegit) claims to refute a point but they end up presenting their own point which is 10 times more ridiculous than the original one.
