See, this is the kind of thing that blows my mind. To me, the alien hypothesis is almost easier to digest. This would be like a farmer hand-turning the soil in an entire field just to plant a single single in the center; so much work for such a small gain. How do they know?! I understand why they do it now; it's an instinct that has aided survival for millions of years. But, where does it originate from? Nature never ceases to amaze me! Thanks for sharing.
RESTEEMED!
