Because we only worship one god (Allah SWT), on the other hand you dont even know, who you follow, you dont even know the names of your gods? do u? since you have limited knowledge, just keep it to yourself, dont make a fool out of yourself and your 5 million gods. P.S isnt it easy to worship one god, instead of 5 million, lol go figuer it out!
Worshiping one god doesn't seem to have helped you much. May be you should try diversification
