It's bit vague at all.. Is probably the most asked question since we started asking questions in fact... And I believe the answer is different for each and everyone one of us... How do you want to be remembered is probably a good a starting point as any
The only time I would worry about the meaning of life is if I was the only person on earth -no other creatures. Even Adam wondered about the meaning of his life when he noticed all the animals had mates but he did not.. So when he complained to God about his problem God created Eve for him Actually Eve was the 3rd woman God made for Adam; the first two were not suitable.
The story of Lilith and the other (un-named) woman was declined inclusion in the bible. Adam was said to be actually having sex with the animals before he asked God for a woman mate . So God created Lilith but she rejected Adam and ran off to corouse with the demons and produced many demon offspring. Then God made another woman but she had so many imperfections Adam rejected her. So finally God took a rib from Adam and made Eve. You can google 'Lilith' for more info. There was a book (I forget name and author) that wrote about a lot of interesting material that was declined inclusion in the bible. I wanted to order it but has been out of print for some time.
