eli5: What is the bootstrap Paradox?
gpt
An event that has no ultimate cause due to a time travel loop.

Your future self arrives in a time machine to give you the plans for a time machine, so you can build the machine and go back in time to give yourself the plans. 

The plans have no actual original creation. This is a  bootstrap paradox.
