No, but why postulate one if you don't need him in your explanation?
And no, I'm not familiar with Last Thursdayism, but I'm sure you'll fill me in, and I feel certain I'll be offended. ; * )
Last Thursdayism says that the Universe, and everything in it, was created last Thursday, along with our (false) memories of everything that happened prior to that.
It's also not falsifiable, just like your creator.
Sorry, but it's falsifiable by my reason and common sense. One cannot for a minute claim that that is as logical as the two choices for life: creation or accident. One of those choices will turn out to be true in the end.
Because if you're a bible believing Christian you know that he desires acknowledgment for his creation. That is not too much to ask considering he gave us life.
