Evolution is not scientific.
It fails the Scientific Method
The theory of evolution states that all the diversity of life we see today arose from a single common ancestor which itself arose from an inorganic form billions of years ago. No scientist was around billions of years ago to see this happen, nor have they ever observed one kind of creature changing into another which must have occurred if evolution is true. Evolution has never been observed in any form, EVER. No events, including evolution, from the ancient past can be observed, repeated or measured, the three immutable properties of the scientific method.
But evolution is logical.
Otherwise, you suggest what? That God poofed into existence every creature on earth? No one was around back then to see God invented all the different animals yet you choose to believe that hypothesis. Why?
Can you show us a new species? One that God invented recently? One we are not related to?
So were the first giraffes babies or fully grown mature adults?
