If evolution is true shouldn't we find living organisms or fossils with half-developped important organs such as half a lung or half an eye?

Answer 1

Yes, if evolution were true we would find fossils of half-developed organisms. However, no such fossils exist on the Earth.

Answer 2

Evolution doesn't necessarily produce incomplete or half-developed organs because intermediate stages can still provide a survival advantage. Incomplete structures, like half an eye, could provide some function, such as detecting light, which could be advantageous in survival. Additionally, many transitional forms with different stages of organ complexity have been found in the fossil record.
