Could the devil have created all theses millions of religions to confuse people about God ?

Yes.

1Tim 4:1 But the Spirit says expressly that in later times some will fall away from the faith, paying attention to seducing spirits and doctrines of demons, 4:2 through the hypocrisy of men who speak lies, branded in their own conscience as with a hot iron; 4:3 forbidding marriage and commanding to abstain from foods which God created to be received with thanksgiving by those who believe and know the truth.

In the Catholic Church, priests are forbidden to marry and members are commanded to abstain from meat on Fridays during Lent (it used to be year round). Where do you think those teachings really came from?

Only the Catholic Church has the fullness of truth. However, the Catholic Church rejects nothing that is right, true, or good in other religions.

A person can battle the devil using fasting and the angelic psalter of Mary.

The reason that there are so many different religions is because there are so many cultures. Each culture demands a god that tells them that they are right.

You will never find a case of people who support slavery, having a god who does not. Nor will you find a culture that does not allow slavery having a god who does.

Cultures do not obey their god, the god must obey the culture. The christian god had to change his mind about slavery and divorce, because the culture changed.

Whoever created religions, it does not matter. No religion knows God. Learn to love humankind and start doing good to the needy persons you come across in life.

People created religions, and all the gods.

All religions teach different things about God. Only one could be teaching 100% truth. If they all taught 100% truth then there would be only ONE (1) religion, not millions of different ones.
