Questions for theists.

[Ace Otana]

Ace, why would you make the mistake of equating purpose and importance with size and scale? Given this same fallacious logic you’d have to say that an obese man is more important than a newborn child simply because he is bigger. Humans can be a speck in the grand cosmos and yet still be one of the main reasons the cosmos was created in the first place.

You missed the point. If we are just tiny insignificant specks then that is what we are. Feelings and desires mean fuck all. If you can't handle the fact that NOTHING suggests the cosmos was created for us then that's your problem.
Also it's a bit arrogant considering we don't yet know what else is out there. Perhaps there's an alien race that's important and not us. Perhaps the universe was created for them and not us. So why don't we just state that we are small and there is no reason to suggest we are significant.

Why would you create a sense of purpose if you know that there really is not one? Isn’t that a form of self deception?

My purpose in life is to live, and enjoy my life as much as possible. Care for loved ones and to archive all the things I want to archive. I've created a purpose for myself. Why? Well why not? Where's the deception?

Notice that the statement that life has no purpose was also stated as a belief, religious people are not the only ones who hold beliefs.

Stating what we know now is not a religious belief of some kind. Otherwise anything we know now could be considered a religious belief. There is no reason or evidence to suggest that we're special or that all this was created for us. In fact just about everything can kill us.
