Should I go back to my old job?

Hello! I need advice for my current situation.

I was working at a job for 16 an hour. I got a new job offer for 18 . After my two weeks notice from my 16/hr job, I got fired from the 18 hour job for some BS reasons. The 16 job mentioned multiple times theyd be happy to take me back. Should I go back to my old job? I dont want to seem like im crawling back so what excuse can I give them instead of telling them that my new job fired me?
