You may also be referring to the diet restrictions in the Old Testament, you weren't supposed to eat swine...was it rabbit as well? This was changed in the New Testament with the new covenant with a vision of Peter in the book of Acts. Christians are free to eat bacon!
Yes jw's are usually nice very helpful people! Especially when they are preaching, but usually nice in general.
in genesis there was not a first day until there was an earth. It says God created the heavens and the earth in the beginning. Then there is only water on the earth. Then there is light, and that is the first day.
I feel that it was all written from a human standpoint and very simplified, yes. And each creative day was millions or billions of years.
