Why not just plant everything immediately? Why take 13 .82 billion years before putting Humans on Earth?
Because it's a very smart way of designing things.
There are currently product being made that have been "designed" using an evolutionary process.
Games today have more and more content created by algorithms, and more of them are using "genetic algorithms" for that purpose.
The reason is, it's faster, more creative, more dynamic, and even surprising to the "designer" him/herself when things show up they never though of.
It's just plainly smart. To have to think of every detail by hand and make it by hand takes time, effort, and not as surprising.
You either accept Evolution or not. And If you do, saying stuff like God's the force behind Evolution, or God has created evolution is meaningless because when you can create stuff from scratch, why create Evolution?
Because creating a process like evolution is a sign of a higher intelligence. Hand crafting every piece by hand corresponds with the old potters in the old time that had to make the clay by hand and the pots by hand and paint by hand... yada yada.
Why not just make the products? To mess with smart people who study science?
When I draw, I experiment by doing things random. Many things that are "designed" comes from accidental things. Then you improve details over time. Trial and error actually works. That's how cars were made. Airplanes, and many other things have been developed by trial and error.
For instance, if your cell phone is so perfect, why is there thousands of designs, and why has it changed os much over the years? It should be perfected and not have any need of improvements. But for some reason, we discover constantly new things we should add to the "phone". New games, new apps, etc. The world is in constant flux. God is in constant change. That'w what life is, change.
To change and improve is what is smart. To have a God that imitates old smiths from the 18th century doesn't show a smart, mathematical, practical God. We design and use tools to help us design. Are we better than God since we can but God can't?
