If you drilled one end of the hole on top of a mountain, and in a valley on the other end, you should be able to pop out of the hole.

"...morals that America was built on." What I said has shown a lack of morals to you? I think it's easy to see who is being judgmental here. Do I owe you some gratitude for being an "elder, and a minster"? I'm going to be old some day and I don't wish for someone to pacify me because of it. I want people to be honest and try to be logical. And is my status as a farmer any less valuable or respectable than a ministers? If there is a chip on your shoulder that is not my fault.

When my cousins and I were very young we thought we were digging a hole to China. How funny to think of that now.

im just thinking but if he eventually stopped going back into the hole, would he end up stopping right in the middle? and if he did, would he like get crushed in all directions?

I couldn't agree more. It's hard to have a discussion!

"And items like this, that are portrayed all over, in all media. Is what in turn has caused a dumbing down of the world. Which is on purpose. So the elite can control us more like sheep just like the old days of peasant and kings."

What does this have to do with theory and physics? Why do you say things that aren't pertinent to the conversation? Your just making planting arguments it seems. Back on topic. If you don't like easy to understand theory so much why even watch NOVA? Bigbang!

rondus do not bother debating theology with this man. Have you looked at his page. He is set in his ways and might never change. There are enough people that believe in him and his "mission" that he assumes the position of minister and teacher. It's obvious he has an agenda and since you have not complied then do not expect him to be reasonable. Think about it, he has called himself a minister over and over again when we never asked nor was it called for. Nobility comes in action, not words.

What do you mean when you say "video:" and "ron:"?

And "'s" shows possession you meant "smartasses" and even if you meant to use an ' you should have said "smartass'"

I point this out not to be a jerk, but to show you that just because you're an old minister doesn't mean you're right.

I just Googled Romans 13:4.

It strikes me as odd that God can say "thou shall not kill" and say that loves everyone, but at the same time be fine with his creations (whom he loves) killing each other when a fallible, self ordained to a position of power person deems it to be necessary. Especially when God ofers on guidelines to making these judgements. Perhaps I'm too young to make sence of these contradictions.

That was exactly 500 characters. YouTube needs to let us type more.
