A big problem for Evolution?

[Sword_of_Gardenia]

Ok, here's what floors me about evolution. First of all, if species have been evolving over time, why don't we see species today that are in the intermediate stage of evolution? A creature halfway between a bird and a reptile? Or maybe a fish (or some other organism) still trying to evolve into some unknown new creature? If evolution is completely fact, and things don't stop evolving, there would be organisms that are still changing, developing. Secondly, at what point did organisms start reproducing and to start needing another organism to reproduce another? When did we go from asexual reproduction to sexual reproduction? Did sexual organs just pop out of the blue? Were they completely, perfectly functional without any mistake even when they were not quite developed? And at what point was that? Thirdly, Darwin is extremely uncertain throughout his writings (see link). I'm not saying anything against science, I think it has greatly improved life in general. It's evolution I have a problem with, and what I don't consider "true science" as nothing can be proven.
