(np) 1. The assertion that all existence sprang into being this past Thursday, with all memories of sentient beings created in situ. The Universe, and everything in it, was created last Thursday, along with our (false) memories of everything that happened prior to that.

A: "There's lots of pieces of evidence that prove that Last Thursdayism is true but we can't go into that right now."
