It's funny you should say this.  Way back on the last Friday in August 1991 a friend and I were on a very enlightening acid trip.  We came up with this theory that humans were planted here, in the Caspian sea area like 10,000 years ago or so which would make us feral. This explains why we do nothing but cause damage to the planet, hell most of the time when we try to fix problems we created we make it worse.  All this adds up to the possibility we are not from this planet.
