Who created photosynthesis? god vs. rock   stance: god made plants so therefore he made photosynthesis:
Seeing as how I don't believe in the Big Bang theory and I believe God created all per Genesis, I have to say that God created photosynthesis.
Although for those of you who disagree, I wonder just how likely it is that you think photosynthesis evolved. Something as complex as that process occurred by evolution/accident?
It is things like this that make me wonder how we can't all believe in a supreme creator whether it be God, Allah, Vishnu, or any other god that people choose to worship. It just seems that somebody/something had to design it all at least in the beginning.
