Meaning to say, evolution can be determined by fossils? And where can we find fossils? How would they know that what they have is already a fossil?Thank you sir for your reply.

How did scientists know what happened millions of years ago if no one was there to see it? And if we are going to teach this to our students, what is the best instructional material to used? I am newly hired secondary teacher. I am just preparing myself on this topic. I hope someone will reply to my post. Thanks in advance.
