"Why does god need a starship?"
You're asking the wrong question. It's like the way people look at tithing - the whole give 10% to your home church thing? Most people see it as giving 10% of their money to church. Instead, they should see it as being allowed to keep 90% of what God gives them for their own use.
It is also like asking why the Jews are the chosen people according to Judeo-Christian belief. It's not that "They're special, therefore God chose them", but rather "God chose them, therefore they're special."
God repeatedly says in the Bible that the land which He brought the Hebrews to from Egypt is His land, and is not to be sold or divided forever. It's not the Palestinian's land, it's not even the Jews' land - it's God's land. Why? I don't know. But He chose to plant the Tribes of Israel there, to be caretakers over the land.
So, what does God need with a starship? Nothing - He doesn't
need one. But if He chooses to make use of one (just like He chose the Jews, or the Land of Israel, etc), then, well... that's
His choise, ain't it?

Now, of course, none of any of that seems to be relevant to you in the slightest if you don't hold a Judeo-Christian belief system. I don't expect it to convince anyone that "Hey, he's right!" or anything like that. It's just there to explain, from an insider's point of view, what the deal is. It's what I believe in, personally. You all know me well enough to know that I'll never take my beliefs and impose them on anyone in any way shape of form - heck, it's mighty unlikely I'll even take any of this outside this thread (unless similar threads arise - which they do). But I hope it may help some of you see the reasoning going on inside Pat - and my - heads regarding this whole issue.
