For practical purpose yes.
Most people don't have any problem mixing things like christmas, new years, shinto, buddhism, ancestory worship etc.
However, just about all major religions originated in Sumer cradle of civilization and morphed.
It all started in Sumer, cradle of civilization. They combined lots technology, such as pottery, metal, mason, water, sewer, plus fine formula for structure of an empire. Basically, elite using a story[lie] to gain from others.
Religion is story of gods which enable priest to collect money from followers.
Hero is story making loyal blood special, such as king Arthur.
Story about fake birthday and santa exist.... Elite merchants benefit since it brainwashes people into unnecessary spending which make them broke. Remember the story of couple, she sells hair, he sells the watch? It is NOT necessary to buy JUNK for other person, in fact it would been better if they did not and save the money for a future kids. It is a warm story that brainwashes people into becoming shopping addict.
Formal massively structured religion started in Sumer. And it was copied over and over again with various changes over time and location. Not much different than language or culture.
