I disagree with you on two points.
Evolution does not blaspheme God. It challenges the Bible and Koran, but does NOT challenge God. I don't accept the Koranic and Biblical version of creation - so I don't have to tell you how plants requiring photosynthesis can survive for eons without the sun. You are mixing your hypothesis - you are the one who believes that plants predated the Sun. I don't.
God is too magnificient to be tied down to one religion's view point.
Yes, it most certainly does challenge God. Either it happened the way we're told it did in scripture, or scripture is a lie and thusly God who inspired it becomes a liar. It is a direct challenge to both the scripture and God. Evidently you know just enough about scripture to be dangerous or a bad liar and I don't know which. As far as the plants predating the sun, that's scripture. I don't pick and choose what scripture to follow.
As far as your commentary on God's magnificence, if you revered it so much, you might have more respect for what is His word. I don't know what group you're pandering for; but, it's not gaining you any credibility with me.
