Part 1 design of life
One of the most persuasive argument for theologists has always been this idea that creatures were somehow designed. Paleys watch and watchmaker is an example of this. This was essentially an argument from incredulity. What they, and you, are saying is I cant see how this occurred therefore goddunit. To illustrate the ridiculousness of this here is what they, and you, are doing:
We cant explain design [SIZE=+3]→[/SIZE]Goddidit
We cant explain it [SIZE=+3]→[/SIZE] We can explain it
The above is enough to illustrate the fallacy involved, but there is something even stronger that can be brought to the table. The design in creatures has been explained natural selection. The DNA molecule isnt copied perfectly when organisms replicate creating new variation. Some of new variation is better suited to the environment meaning the creatures possessing this advantageous variations are more likely to reproduce and pass this advantageous variations to the next generation. The environment is selecting those creatures best suited to survive and reproduce within that environment. This is the process that has designed the creatures on this planet to fit their respective environments.
Did you know that using the concept of natural selection scientists can write computer programs that produce designs far better than human designers can? For example, genetic algorithms that mimic natural selection
can design satellite orbits that outperform those designed by humans?
When you talk about the design of creatures being evidence of god, not only is it flawed from purely logical perspective, it also flys in the face of the design process of natural selection that science has discovered to be the cause of it.
Part 2 design of the solar system
How are the planets so perfectly aligned so they do not collide? How are they all spherical in shape? Who/what designed this most wondrous of cosmic dances?
That designer is [SIZE=+3]GRAVITY!!!![/SIZE]
Here is the idea is 5 steps.
Step 1 - Matter attracts matter because of gravity. If you had a cloud of stationary matter, of which most was hydrogen, out in space then gravity would, given sufficient time, cause it to collapse in on itself. Such clouds of matter undergoing gravitational collapse have been observed by the Hubble telescope.
Step 2 As clouds of matter collapse under gravity they begin to spin (the spinning is a consequence of a collapse with non-uniform density). Some of this hydrogen material, at the core of the cloud, become a new star. This process of star formation
can be observed with sufficiently powerful telescopes.
Step 3 Some of the material, including some of the heavier elements, will be thrown outwards by the spinning cloud. Some of this material may, provided it gained sufficient kinetic energy, go into orbit around the central protostar. This material will, under further gravitational collapse, coalesce into rings that will become protoplanets.
Step 4 After sufficient time the protostar will stabilise under gravity and undergo the process of nucleur fusion. Basically the sheer weight of the material will force hydrogen atoms to fuse into helium releasing large amounts of nuclear energy. This is how our sun operates. The sheer weight of the suns material under gravity is forcing hydrogen to undergo nuclear fusion, releasing enough energy to counterbalance the force of gravity creating what is called stellar equilibrium.
Step 5 Those protoplanets will similarly stabilise under gravity to become planets. These planets do not have enough material to be forced into nuclear fusion like the sun was. These planets also contain greater proportion of heavier elements due to lighter elements escaping the unstable protoplanets atmosphere, and due to the bias of heavier elements being more likely to gain momentum during the original clouds collapse.
In short, gravity explains why the planets appear to be in such perfect orbits. It should also be noted that there are many asteroids, comets and meteors orbiting the sun that are in much less perfect orbits, which
sometimes leads to collisions[/quote].
Part 3 design of the universe
Until I can get what purpose the universe was designed for this doesnt need to be addressed.
The claim that the universe was designed for life is ludicrous given the absolute scarcity of places that life could survive. If I found an iron atom in my house I would be out of order in claiming my house was designed or fine-tuned for producing iron. So why is it not out of order to claim the universe was designed for life? The ratio of habitable space to the universe is far worse than the ratio of an iron atom to my house.
The usual response is to say that the universe was fine-tuned in order to make life a possibility. Can someone show me that doubling the force of gravity (for example) would prevent life from arising? Life as we know it wouldnt exist in such a universe but can you show me that no other form of life can exist?
Look at the variety of lifeforms that have every existed on our planet every single one is adapted to their environment. The environment was not designed for us, rather we (by we I mean all lifeforms) have been adapted to the environment.
