I have yet to see a psychic who could manage a decent stock portfolio, let alone one who can accurately predict major events in the future and see into the past. So we got past the bow and arrow stage just in the nick of time? *Phew* Well then, bring the aliens on! Now we've got tough-talking space marines with cool-looking body armour to face them, some of them even carry really huge clumsy guns that are just perfect for close-quarters combat. So I take it that in addition to giving us things like bread, ceremonial burials and cave painting, the Neanderthals were also highly skilled negotiators.
