Hi Suedonim. You mention the Stonehenge era and those who worshipped the sun god. Those people would still have heard of "our" God, but they chose to be pagans. Paganism has been going as long as humanity really, but it doesn't mean to say they didn't know any other ways. I'm afraid that if you know about God and deliberately choose to ignore him, or turn your back on him, you won't see Him in Heaven, but then you won't go to hell either. Hell was created by the devil and basically people choose to go into hell by turning against God and siding with the devil. These pagans would be judged according to what they had done in their lives just as we all are when we die, but certainly turning their backs against God would not stand them in good stead. Your guess is as good as mine as to what happens to them. If you are a Catholic you would believe in Purgatory, where sinners go who are not pure enough to get into Heaven, but not evil enough to join the devil in Hell. They believe that our prayers can eventually free these souls from Purgatory. Others believe they are permanently in a state of limbo. Whatever.
As for being a member of the judiciary. Christians can do this, that involves making a judgement based on evidence, and that judgement must be free from 'all reasonable doubt'. They are not judging that person's lifestyle, they are meant to judge merely the crime they have committed, whether they are guilty or not, how much time should they serve, etc. Jesus told us not to judge without first seeing our own failings, if we are to condemn others, we should first condemn ourselves for our failings. No-one is perfect so really, no-one has the right to condemn others. Christians should merely lead by example and by telling others of the Good News. Jesus also told his disciples not to stay in areas where they were not welcome, so if someone really doesn't want to listen to the Good News, we should not push the subject.
As for dinosaurs and so on. I believe they were part of God's creation, but perhaps because they were incompatible with man they had to go. People say that dinosaurs are not mentioned in the Bible, but God says that he created animals of every kind, he doesn't give a list, so I think we can assume that dinosaurs were in there too.
Hope this answers some of your questions. I must say it's nice to get away from homosexuality for a while!
