In response to Alcars's last post, I also follow my heart on such matters discussed in this thread, which is probably fairly obvious. My heart tells me God created everything and everyone, and that's all that really matters. My heart doesn't care how it happened, but that doesn't mean my brain isn't curious and sometimes wonders if it could be this way or that. I know the difference between my brain and my heart, and I think when combined, they both work at their full potential.
