religious contradictions, page-68

Hi All,
Wow - I've just read (most of) that whole thread!
I'm new here, so please forgive any intrusion, but it would really help me understand some of the apparent "contradictions" between the Bible and scientific beliefs if any of you inclined to do so would answer a couple of questions regarding your beliefs. If you could give a one sentence explanation of why you hold that belief, that would (I think) be really interesting too.

1. Approximately when did life on earth start?

2. How old is the rest of the Universe?

3. Did dinosaurs ever exist?

4. Did we, and animals, evolve, or are we pretty much unchanged from original (created) "templates"?

Many thanks,

Dan
