I like it...
I'd much rather have someone who is ready to defend the faith, bring these topics up, and have people learn from them, versus people hearing about them from atheists, or their quasi christian friends. I love these topics, and, if in fact some of the alternate view are true, then how is it a bad thing to discuss them? As has been said, we want to seek truth.
These discussions just prepare people, for what's out there.
I do believe we all, animals and humans alike, could easily be sustained by photosynthesis with a miraculous flip of the switch if God wanted, not to mention God's Glory. The same way light can be without the sun due to God, why not nutrition without eating due to God?
It seems, "Food" may very well be for pleasure only, in Eden and Future glory.
I mean, so many of the beauties of creation, could have been done in a much more drab fashion, with the same practicality. I know science explains it all away due to evolution and survival of the fittest, but God could very well have designed it for His own Glory, as well as for practical use in some cases.
So, don't know where I stand, but, I find it valuable, relevant, and fun.
