God created everything through His Word - not through a "mechanism":
(Gen 1:11) Then God said, "Let the earth bring forth grass, the herb [that] yields seed, [and] the fruit tree [that] yields fruit according to its kind, whose seed [is] in itself, on the earth"; and it was so.
(Gen 1:20) Then God said, "Let the waters abound with an abundance of living creatures, and let birds fly above the earth across the face of the firmament of the heavens."
It is God Himself said there is no Evolution:
(Gen 1:24) Then God said, "Let the earth bring forth the living creature according to its kind: cattle and creeping thing and beast of the earth, [each] according to its kind"; and it was so.
So, you created your own god who requires a mechanism called evolution for creation, to fit your theory. hmm..
The God of the Bible clearly speaks out, there is not a single living creature that will ever going to bring forth creature of another kind, in other words, no evolution.
