There is no science to suggest that the time frame for evolution is too short.
Evolution is a fact... or at least as factual as anything can be in science. To put it bluntly, modern biology doesn't make sense without evolution.
Now wait a minute..a fact is something that can be provable,demonstrated and replicated.
Show me how that applies to the whole of the theory of evolution.
I ask you again to prove by that means how a reptile suddenly began to bear live young,grow hair/fur and have milk glands.
You can`t but somehow have to believe it happened.
That takes faith.
Your statement regarding it is as factual as science can do in light of that shows again it is a matter of faith,you make the argument against yourself.
