The concept of "Gods" is present in many different cultures and religions, and the timeframe in which they are believed to have existed varies greatly depending on the specific belief system.
* Ancient Polytheistic Religions: Gods and Goddesses in mythologies like Greek, Roman, Egyptian, Norse, etc., are not considered to have existed within a specific historical timeframe in the literal sense. Instead, they are part of the mythological stories and beliefs of those cultures, dating back thousands of years.
* Monotheistic Religions: In monotheistic religions (Judaism, Christianity, Islam), God is typically seen as eternal and existing outside of time. There isn't a concept of a specific year in which God began to exist.
Therefore, there is no definitive answer to the question. The perceived existence of Gods depends on individual belief and the specific religious or mythological context.
