Is it just me, or is it kinda weird that it seems that according to the bible it used to be ok to marry and have kids with your siblings?

@TheWildEcho Pre marital sex, catamites, and homosexuality was commonly practiced all around them. Those sorts of things weren't weird to them at all, otherwise laws against them would have been pointless.

@AkioTsukino but do you think it would be accepted like it is today?

@TheWildEcho I think it was accepted much more then. Temple prostitutes, catamites, polygamy, incest, pedophilia - consider Sodom and Gomorrah. Even in what we would think of as traditional marriage things were much different. Mary was only 14 or 15 when she married Joseph, who was probably in his early 30s. People didn't get married because they "love" each other, it was a practical partnership. Things were different then.

@AkioTsukino yes but that was a lot later than Adam's day which is when the op was refering to

@TheWildEcho Adam's day was a thousand years, and encompassed, from Adam’s creation to the birth of Seth, for example, 130 years. Seth was born after Cain killed Abel and they were grown men at that time. They may have been as old as 100 when Abel was murdered. During which time Adam and Eve had an indeterminate number of sons and daughters.

I think when people read the Bible they think in linear terms not unlike their own, like the events told there are compressed in time, instead of how they may have actually unfolded. Genesis 5:1-29; 7:6, for example, contains 1,656 years.
