Do some research and stop believing everything you hear.... Evolution is as demonstrable as gravity? Lol...What does that have to do with evolution, you redirecting nutjob? I'm not going to entertain your strawman bullsh!t, stick to the topic at hand.
Evolution is as much demonstrable fact as gravity. There is NO argument. Does that mean that we don't have observed gravitational anomalies that take further research to explain? No. Does that mean that we don't have small portions of evolution that are unknown to us and may take further research to explain? No.
Evolution is like a 5000 piece puzzle with 2-3 pieces missing. Intelligent design is like taking the same 5000 piece puzzle, tossing all of the pieces in the trash, and throwing the Bible down in their place while saying "Yep, solved that one!". You're throwing out everything that's been observed, tested, and makes sense while inserting something that is baseless, untestable, and unnecessary.
Perhaps you could demonstrate just one example then huh?...
