I agree. Honestly, I think there are a lot of questions about Evolution which make even the experts think hard.
My feathers only get ruffled at the mention that Evolution is a religion. 
Here is how I look at science. I’m 26 years old. My career is just starting. If we had all the answers, then why would we need scientists? My career would be over before it began.
The same with evolution. There are many people working on filling in the blanks and gaps that creationists exploit to try to show fault. We do know claim to know it all.
It is shocking how much we don’t know in every aspect of science. If your science class gives you the impression that we have everything but evolution worked out, then that is the real tragedy. Every chapter of your science book is glimpse to hundreds of people who are today trying to work out the hard questions.
