Monotheism is the belief in one god. I suppose a religion would be more specific to your question, however, seeing as that would by definition mean that everyone in hat religion worshiped the same god.
They all worship the same creator God, the result of which is that the majority of people on earth worship the same God.
Why do people worship American God or anything else? Same Reason
Kind of. Muslims worship Allah, which is Arabic for God. Christians worship the same God, they just don't call him Allah. More importantly, Christians worship Christ, which Muslims do not believe in.
Yes we do. We worship the same God as the Jews. The God of Abraham and Jacob. The same God that created everything.
The same way most other cultures do.
The purpose of a worship place is because so people can pray to god and be in an environment with people with the same believe and with the same religion. Another reason is that so they be in touch with there god (unless they are Buddhist as they do not believe in a god but just there leader) talk to god and show respect towards god.
All christians, Muslims, and Jews worship the same God
People worship in various faith for they believe in their faith, which is the same in Islam. People worship Islam because it is what they believe in. They believe in Islam as being the final revelation of God.
