Atheists claim that scientific knowledge has replaced the need for appeals to God to explain the universe. This is easily demonstrated to be false, as countless legendary scientists found it necessary to invoke God to explain First Causes in the universe. Isaac Newton could explain what gravity did but not what caused it, and believed God kept the universe in motion. While Albert Einstein's theistic views were complex, he too could not explain the universe without God, and famously derided chaos in the universe by stating "God does not play dice." Even in the 21st century, no scientific theory attempts to replace appeals to God in explaining the universe's existence.

Indeed, atheists have merely usurped the mantle of "science" to disguise unevidenced assertions. They claim that evolution has been proven as scientific valid, that evolution necessarily proves abiogenesis, and that abiogenesis precludes God and design. The first claim is refuted by numerous theistic scientists, the second is a belief, and the third is a philosophical absurdity. Atheists believe the universe can be explained without recourse to God, but have no actual evidence to back up their assertions.
