Have humans always needed to drink water in order to survive?

A Bible/health question I have had for a long time (possibly for creationists out there) do you think Adam and Eve needed to drink water in the garden of Eden or do you think their raw vegan diet options were so lush and filled with moisture that it wasn’t needed?

(Perhaps for non-creationists), do you think that water has been a necessity for humans to live since the beginning of their existence? How much water? What kind of water?

In addition to thinking about water…

Were humans carnivores or vegans since the beginning of their existence? How do these beliefs effect your permaculture philosophy and design? Have your beliefs changed over time?

…
I was raised vegetarian and have eaten vegan for a season… now I eat biblically kosher but I try to eat seasonal, local & organic when possible.

Religion, education, international living, budget, health challenges and allergies have all influenced my dietary decisions.

I have read lots of different books, including autobiographies, and interviewed many people about their health journeys (and permaculture journeys.)

Looking forward to hearing about yours,

Hi Alana.  I haven't ever lived on a raw fruititarian diet, but I've heard from multiple people that they don't need to drink water on that diet.
