Believers!! Don't mislead people

[Losty]

However, if you ask an atheist whether or not it's impossible that a god exists, the answer could be a yes, no, maybe, pretty much anything.

That what confused me, and what then is the difference between an Atheist and Agnostic. There are many answers but it is not consistent, ie. as one conclusive conclusion.

You cannot be agnostic.

You can be agnostic atheist or agnostic theist or agnostic deist but not just agnostic. There's a thread about this you should check it out.
