How about this: 20 step proof that God exists and created the universe, purely based on simple observation and logical thinking (since obviously bible quotes don't work)
1) Every effect has a cause which is greater (that is, more complex) than itself.
2) The universe is an effect which must have a cause which is greater (more complex) than itself.
3) The universe exists. (Pantheism is wrong)
Therefore,
4) The cause of the universe exists.
5) The universe contains the personal and the moral. (We humans are personal and moral.)
Therefore,
6) A (at least) personal moral cause for the universe exists. So the cause can now be called "He" not "It".
7) The universe does not create something from nothing (by observation), yet it is something (See #3 above )
8) Therefore, the universe had to be created from nothing (or from something that was ultimately created from nothing.)
Therofore,
9) The personal moral existing cause for the universe can create (i.e., a personal moral Creator exists.)
10) If the Creator-Cause were finite, then He would have another Creator-Cause who would in turn have a Creator-Cause and so forth.
This leads to an infinite regress of causes.
...CN --- ... C3 --- C2 --- C1 --- Universe
11) But that would mean that at least one finite Creator-Cause would be either (a) self-caused or (b) uncaused. That is impossible because (a) a being cannot precede itself to cause itself and (b) nothing finite is uncaused (by observation)
Therefore,
12) All the causes cannot be finite (non-ultimate) causes.
Therefore,
13) The personal moral existing Creator-Cause is infinite (i.e. ultimate)
14) The infinite cause must be eternal because eternality is infinity applied to time (and no meaningful statement can be made about space without reference to time).
15) An infinite eternal Cause could not change (since anything He would change into, He would already be).
Therefore,
16) The Creator-Cause must be all-knowing, all-powerfull and all-perfect (otherwise He could change).
Therefore,
17) A personal, moral, infinite, eternal, immutable (unchanging), all-knowing, all-powerfull, all-perfect Creator-Cause exists.
18) Such a Being is worthy of worship.
19) A being worthy of worship can be called God.
Therefore,
20) God exists.
To sum it up:
1) Every effect has a cause.
2) The universe is an effect.
3) The universe has a cause which we call God.
