No Excuse?

For ever since the creation of the world His invisible nature and attributes, that is, His eternal power and divinity, have been made intelligible and clearly discernible in and through the things that have been made (His handiworks). So [men] are without excuse [altogether without any defense or justification]
Romans 1:20

So nobody, anywhere on earth or at any stage of history has a valid excuse for not acknowledging God? People are purposely ignoring the clear facts in the world around them that there is a God?
