The atheistic worldview presupposes the non-existence of any gods. ...For the record, there are two ways of looking at strong atheism. The first is just a statement of opinion: The strong atheist has the opinion that no gods exist; what supports or justifies this opinion is stated separately, and in individual cases might not be sound.
Strong atheism is complete denial of the existence of deity in any form... To date, there has been zero conclusive scientific or philosophical arguments that disprove the existence of divinity. One who professes to be a strong atheist must then prove that he or she is omniscient (all knowing).
Here is the contradiction. A strong atheist must deny divinity by attributing man with divine abilities.
The more philosophically aware strong atheist says that she concludes from the facts in evidence that no meaningful, relevant notion of god she's ever heard about actually exists. If additional facts were to be discovered or a substantially new conception of theism were proffered, the conclusion would have to be re-evaluated.
