OK, I know some people don't like it when I get pedantic, but sometimes I just can't help it.
Your hands and brain are not tools. They are parts of you, and what they can do are your intrinsic abilities. Tools are the things we make to extend our intrinsic abilities. We can all dream up new rocket designs, but many of us depend on computers to work out the details and ensure they will (probably) fly right. We can hold tubes, balsa sheets, etc. in our hands, but we need knives or saws or something to cut them to length and to shape. Etc. It's only those ability extenders that are tools.
And God - if you believe that stuff - is even further from being one of our tools. As the source of our intrinsic abilities, He is a step away from the objects that extend those abilities since the "chain of creation" if you will goes God -> us -> our tools. While He my provide rocketry related miracles, like the safe recovery of a rocket after the main chute opens over a mile up, those would be things that He hath done, not things that we used a tool to do. (Besides, who really wants to say "God is such a tool"?)
So you hands, your brain, and your deities may be important, but they are not tools, and so they are not germane to this thread.
OK, I'm done now. Sorry.
