I still refuse to believe that evolution could create flying creatures. Not only are birds perfectly aerodynamic many of them can do things which seem impossible. How can an eagle be flying overhead, see a mouse some 2,000 feet away in a field, go into a nosedive, at the last moment extend its talons, pull up, skim the ground and snatch the mouse and fly away without every crashing or injuring itself?
Practice
Flying was a good idea however it came about. Flying reptiles, flying mammals and the amazing diversity of birds. I think a video of a crow in Russia obviously creating a game to play sliding object down a snowy roof was just out and out humbling. We haven’t got any monopoly on smarts.
I totally agree, the only possible explanation is magic.
