What does Islam think is the problem with atheism?

All other religions such as Christianity are believed to have their books altered (as we believe in Islam) and other religions such as Hinduism are seen as false due to the ideas of demi god. However, atheism hasnt really been addressed in the Quran or hadith because the prophet didnt encounter atheists. What does Islam think is the problem with atheism? Edit:If clarification is needed for this question please ask. By what is wrong I meant part of the reason we arent christians or hindus is because there are flaws with those religions which is why we go to Islam.
