Out of all the Back to the Future theories that I've posted about and read, this theory is the coolest one I have ever seen. Basically, this theory says that all three movies are one big chiasmus.
What is a chiasmus? Well, let's take a look at the nursery rhyme, "Hickory Dickory Dock."
See how that works? Basically, the beginnings and ends are always either very similar or exact opposites. Then, it just goes on like that until we reach the middle, which, in the poem, is "C." The theory states that Back to the Future is a chiasmus.
This theory was created by Robert Lockard. All ideas and picture credit belong to him. And MASSIVE SPOILERS starting in the next paragraph and until the end of the post.

And That's It!
Wow. This is my longest post I have ever done. As of now, this is my 1900th word and it says the reading time is 6 minutes and 21 seconds. So, this theory was created by Robert Lockard and I think it is a great theory. It has few holes and is done very well.
All picture and theory credit belongs to Lockard and right now, I'm just saying a lot of stuff because I'm trying to get to 1985 words.
Just wait till you see what happens when this baby hits 88mph:
