A religion must include a god and a place of worship. Science has neither. If you believe in science you are an athiest. Scientology isnt a religion either, it is more of a cult
But the definition of "religion" doesn't say that a god is a requirement of religion. However, the activities and thinking of mankind in his presumptuousness, suggests that mankind makes himself out as though he were a god. So, religion always has a god, even though the definition doesn't require it.
Your definition doesn't. But as pointed out many times before, the standard dictionaries (those that existed long before "dictionary.com") have definitions of religion that include terms such as "supernatural belief" and "god or gods" in their definitions.
If you want to go by the ancient dictionaries, move into the past. The present dictionaries are the language of today.
There are many words that come into being because someone made them up, and people started to catch on to them, until they were recognized as words. Such words are the language of the day. This is Dictionary.com... the language of the day.
Use it, or build a time machine and go back into the past. Of course, if you did that, you'd be strung up for proclaiming your atheism.
OK then, let's see what this arbiter of good sense (that apparently promoting Astrology on it's main page today) has to say about "religion":

My definition of a religion fits in with *all* the Dictionary.com definitions. Your definition of a religion does not.
