I want to build my own FM radio, however, I do not have an in-depth knowledge of physics and electronics. I need someone to explain how the this FM radio circuit works.
I could try, but I doubt it would make much sense to you, especially if you don't have any understanding of circuits.
You might be better off looking at software defined radio. GNU Radio Companion is a good piece of software, and there's plenty of instructional videos. Plus you don't have to build a circuit, and you can customize your circuit within the program to do multiple things without needing a rebuild each time.

You're probably right, I just want to build an actual radio. Design it uniquely and stuff. Could I buy a premade circuit? or use some sort of software possibly

Software defined radio essentially means your antenna is a physical antenna, but everything else in the circuit is going on in your PC. Really powerful.
There are a lot of kits (ex: https://www.amazon.com/Elenco-FM-88K-FM-Radio-Kit/dp/B004YHZE0G/ref=sr_1_1?ie=UTF8&qid=1503495763&sr=8-1&keywords=fm+radio+kit ), but they're going to teach you more about how to solder things to a board than how to design a radio.

Actually, I think I'm just gonna buy a radio, take it apart, design a new exterior, and put it back in. Once i get older i might actually research how the thing actually works.
be aware that you may disrupt other radios or frequencies and get in trouble if you don't know what you are doing.
Just stick to pre-made radio kits or radios and follow the instructions.
