"Wow! That is so cool how God has created everything to such perfection so that all that there is can exist. It's so easy to see that there is a God, that all you have to do is walk outside and look at the trees and the sky and ask yourself "could all this just happen?" Rom.1:19-20 says 'for what can be known about God is plain to them because God has shown it to them for his invisible attributes, namely his eternal power and divine nature , have been clearly perceived , ever since the creation of the world , in the things that have been made . So they are without excuse'. The way God has created a tree's metabolism to absorb sunlight and the roots to feed on water and the leaves to make air for us to breath is truly amazing. Even a thousand humans wouldn't be able to do this in a hundred billion years. So why do people think that nothing could create everything in billions of years? Well because they are so desperate to break away from God's law and live according to their own laws.
Another amazing thing about the planet earth is this; if the earth was a little smaller its weakened gravity could not hold water or air, and the thinner atmosphere wouldn't provide enough protection against all the meteorites that hit the earth's atmosphere every day, thinner air would make temperatures drop and all of life would die. If earth were twice it's size it's gravity would be too strong and almost everything would be crushed under it's own weight. Also, if the warmth the gulf stream(the great current in the north Atlantic)were not there, Britain would have severe winters in which many people would die. One mistake by 'nothing' would have spelled death for everything, if life had ever even made it to existence.
