1) That is true. My mother tells me that we are from God's light and we return to it. I think it's a nice idea. Here, "we don't stop existing" comes in terms of heaven. 2) Without meeting them, one cannot be sure. Those people exist as mere hypotheticals to me. I can come up with a person and their life and chances are they exist. For them to exist to me, I simply have to strongly believe in it.
I've been meaning to do something about that since I viewed my page on Lynx once. Buttons don't work, so I should probably turn them back into links like before. The index's issue is likely the JavaScript use.
You can make the javascript work, though it would require a little extra work. The page would have to first be in a navigable state, and then be changed by the JS to how you want it to look in browsers with JS.
