I don't understand how the existence of Evolution can be queried. It can be proven in an almost mathematical sense.
They can prove it is possible, but no one can go back in time and observe it.
What I mean to say is, it feels a bit like trying to argue against something like friction. When you assumesthe existence of matter, you can't say friction doesn't exist, much like when you assume life exists, I think it goes hand in hand with Evolution.
ie.
1. People/animals inherit things from their parents. This can be observed.
2. Some people/animals are better at things than others.
3. Sometimes, particularly in 'the olden days', people/animals got into life threatening situations, where they got saved or killed because of characteristics.
Ergo, over a period of time, evolution must happen.
All very silly.
