How could people live 800 years during biblical times?

The notion that people lived for hundreds of years during biblical times, as described in texts like Genesis, is often interpreted in various ways. Some suggest that these ages reflect a different understanding of time and human life in ancient cultures. Others propose that such long lifespans could be symbolic or mythological, meant to convey the significance of these figures rather than literal historical truths. Additionally, some theories suggest that environmental factors, such as a more favorable climate or diet, may have contributed to longer lifespans in those narratives.
