In my opinion

In my opinion a Non Muslim is the same as a Atheist since they don't believe and reject God what do you think ? My question is how can a Non Muslim claim to believe in God and at the sametime reject God's last and final Prophet and Messenger which is Muhammad Jews and Christians both do this is it true that there a verse in the Quran that says that rejecting one Prophet is rejecting al the other Prophets too I just think accepting God's Prophets and Messengers is important because God is giving Human Beings the truth also in my opinion Western Leaders of Western Governments are Atheists because they reject and don't believe in God's Prophets and Messengers therefor Non Muslims reject and don't believe in God.​
