You are entitled to hold that opinion, but it is an unverifiable hypothesis. You state as fact something that is supposition.
When a Christian does that, it is correctly called faith.
Who says I'm not a Christian? When is reads in Genesis that it took six days for God to create the universe does it exactly quantify how long those days where to God?
In the New King James version of the Bible more on the sixth day God created the animals it does not say how they were created, does it?:
24 And God said, “Let the earth bring forth living creatures according to their kinds: livestock, land crawlers, and wild animals according to their kinds.” And it was so.
25 God made the beasts of the earth according to their kinds, the livestock according to their kinds, and everything that crawls upon the earth according to its kind. And God saw that it was good.
26 Then God said, “Let Us make man in Our image, after Our likeness, to rule over the fish of the sea and the birds of the air, over the livestock, and over all the earth itself and every creature that crawls upon it.
There is no mention of how animals were created: nothing about using an Easy Bake oven, animal creation machine made out of diamond and mother-of-pearl, or an angel crapping them out. Nothing.
God gave us our senses and intellect to pursue the truth that is woven throughout the wonder of his creation.
