How has science proven the non existence of a higher intelligence?

In no way do science discoveries dismiss the existence of a creator, if anything it points toward one. Most say that believing in a greater being or God is pure ignorance....but the actual ignorance is from thinking that everything in its chaotic order... just happened to be without any help or intelligence. Scientist have never claimed to have found proof that would dismiss God, yet so many of you claim thats what has happened. If there is concrete proof, as many claim to have discovered through science, of the non-existence in a creator, then I know myself and many others would love to discover this also.
