Atheismus vs Religion
religion
'die Religion' and 'der Atheismus' stand in clear contrast to each other. 'Religion' means a belief in God, gods, or a higher reality, often with rules, rituals, and a community. 'Atheismus' means the conviction that there is no God and no gods. Both words therefore describe a basic attitude toward religious questions, but they answer these questions in opposite ways. If someone has religious faith, you talk about Religion. If someone denies the existence of God or gods, you talk about Atheismus.
Atheismus
Atheismus bedeutet für ihn, dass er nicht an einen Gott glaubt.
For him, atheism means that he does not believe in a god.
Religion
Für sie ist Religion ein wichtiger Teil ihres Familienlebens.
