BCE (Before Common Era) and CE (Common Era) are secular terms used to denote years in the Gregorian calendar. BCE counts years backward from the year 1 CE, so, for example, 500 BCE is 500 years before the start of the Common Era. CE starts from year 1 onward, with 1 CE being the first year, followed by 2 CE, 3 CE, and so on. Thus, the transition from BCE to CE occurs at year 1, with no year 0 in between.
It means 500 years before the birth of Christ as calculated by the early Christians. Most modern scholars believe Jesus was born around about 4BC. Today the more "politically correct" Before Common Era (BCE) is more commonly used.
BC, which is Before Christ, and BCE, which is Before Common Era, actually refer to the same thing. Years in BC/BCE work in reverse. So 12 BC/BCE came before 5 BC/BCE.
No Buddhism was established about 500 BCE. Hinduism has roots going back several thousand years before that.

Chronologically ordering mythologies can be complex, as many developed concurrently and influence one another. However, one common framework places early mythologies such as Sumerian and Egyptian at the forefront, emerging around 3000 BCE. Following these, Indo-European mythologies, including those of the Hittites and later Greek and Roman traditions, developed around 1200 BCE to 500 BCE. Finally, mythologies like Norse and various indigenous traditions evolved later, from around 500 CE onwards.
