According to this theory the world and pretty much everything was created last Thursday. And, it is impossible to disprove this theory even by greatest minds because the theory is not falsifiable..
Why?
Because you may say you have a picture of yourself eating at a restaurant last year. This theory says, you, your restaurant and your memory eating at the restaurant, your picture caught while eating at the restaurant.. etc (the entire thing) created on last Thursday..
