God’s Existence (4:08)
For more reasons pointing to God's existence, see the article, “Is There a God?”
"Does God exist?" could be THE question. Well, here’s three arguments for the existence of God.
1. The Design Argument. It is hard to deny the order and beauty of nature. The amount of intelligibility, the way bits and pieces coexist, order and regularity. From the molecular to the macro, the world leaves us in wonder.
If you paid any attention in biology, you might have seen this.
It’s ATP synthase, a proton-driven molecular turbine that sits in the membrane of your mitochondria, literally producing power in the form of ATP. You might have come across a bacterial flagellum or a human ribosome. You see some similarities?
Is this from the hands of a designer? The only alternative explanation is that everything we see came about by chance. But how can this be, since chance can only be understood against the background of order.
Anyone would look at this sculpture by Nathan Sawaya and know it was created. Let's suppose another theory, that these blocks fell into place. Blocks, raining down randomly, form this structure. Even if highly improbable, given enough time, it can happen.
But chance could not form it alone. The interaction of subatomic particles, the spacial relationship of these atoms within the plastic, the forces holding these atoms together, the friction between the surfaces of the Lego blocks, the platform for the structure to form on, the interaction of gravity and matter -- you would have to assume all these and more before chance could act. So, before chance could work you require order.
It’s the order that we see that suggests a Creator.
2. The Argument from Change. Everything is in a constant state of flux. This is a seed. A seed can grow to be a giant tree. Firstly, the seed cannot bring itself into existence. Secondly, even though the seed has the potential to become a tree, it's not yet a tree and cannot purely change itself.
It needs to be acted on by other things around it. It needs some dirt, some water, some nutrients. For argument's sake let’s say this seed requires seven changers so that it can change.
Now the second question is, are these changers remaining constant or are they themselves changing? Well, they’re changing. So these seven changers each need their changers to change.
Now zoom out. The universe is the sum total of space, matter and time. Space, matter and time are continually changing, but can't bring themselves into being or make themselves change. Therefore, there has to be a force external to space, matter and time, the unchanging source of existence and change.
3. The Kalam Argument. Perhaps the universe does not need a Creator because it’s always been around. There cannot be an unending series of changers changing things.
And here's why…
Here is today. If the past is infinite, there are an infinite amount of days back that way, but it would take an infinite amount of days to reach this day. So this day could never be reached, because an infinite amount of time would have to pass to get to today. So the universe must have had a start and must have had a reason to start.
