Can you explain why your "God" would make two of Jupiter's moons move in retrograde?
Yeah, to make Artiest scientist look dumbfounded as they try to come up with an answer around the "Big Band" theory.

Many moons are the result of planetoids or large asteroids that pass too close to a planet and get caught in its gravity.
The direction of their orbit is determined by which side of the planet they happen to be passing when they get caught.
...
It seems that you don't understand our answers. I'll make it simpler.
1) Take a piece of paper and draw a dot in the center of it. That dot is Jupiter.
2) Draw a line down the page from top to bottom. The line is the path that a planetoid would follow if it wasn't affected by Jupiter's gravity.
3) Draw a circle around Jupiter that touches the line, but doesn't cross it. This is the orbit of the planetoid after it is captured by Jupiter and becomes a moon.
4) Start at the top of the page and move your finger down the line until you reach the circle. Without reversing direction, move your finger around the circle. You are following the path of one planetoid as it is captured and begins to orbit Jupiter.
5) Spin the paper around so that the top and the bottom are reversed. A second planetoid will now approach Jupiter on the other side.
6) Repeat step 4. You will find that your finger is now moving around Jupiter in the opposite direction.
That is why moons can orbit in different directions. The direction of their orbit is determined by which side of the planet they happen to be passing when they get caught.

The "backwards" planets and moons are in no way contrary to the nebular hypothesis. Part of the hypothesis is that the nebula of gas and dust would accrete into planetessimals. Catastrophic collisions between these would be part of planet building. Such collisions and other natural processes can account for the retrograde planets and moons.
The only moons that orbit retrograde are small asteroid-sized distant satellites of giant planets such as Jupiter and Saturn, plus Triton (Neptune's large moon) and Charon (Pluto's satellite). The small retrograde satellites of Jupiter and Saturn were probably asteroids captured by the giant planets long after formation of the solar system. It is actually easier to be captured into a retrograde orbit. The Neptune system also contains one moon, Nereid, with a highly eccentric orbit. It appears that some sort of violent capture event may have taken place. The Pluto-Charon system is orbiting approximately "on its side," technically retrograde, with tidally locked rotation. As these are small bodies in the outer solar system, and binaries are likely to have been formed through collisions or gravitational capture, this does not violate the nebular hypothesis.
Uranus is rotating more or less perpendicular to the plane of the ecliptic. This may be the result of an off-center collision between two protoplanets during formation. Venus is rotating retrograde but extremely slowly, with its axis almost exactly perpendicular to the plane of its orbit. The rotation of this planet may well have started out prograde, but solar and planetary tides acting on its dense atmosphere have been shown to be a likely cause of the present state of affairs. It is probably not a coincidence that at every inferior conjunction, Venus turns the same side toward Earth, as Earth is the planet that contributes most to tidal forces on Venus.
Orbital motions account for 99.9% of the angular momentum of the solar system. A real evidential problem would be presented if some of the planets orbited the sun in the opposite direction to others, or in very different planes. However, all the planets orbit in the same direction, confirming the nebular hypothesis, and nearly in the same plane. A further confirmation comes from the composition of the giant planets, which are similar to the sun's composition of hydrogen and helium. Giant planets could hold on to all of their light elements, but small planets like Earth and Mars could not.

Are You telling us God got confused. You have other people who actually answered your science question.
Now why don't you tell me why Jesus, after his teenage trips to the Welsh Coast with Uncle Joseph of Aramathia decided to import Druidism into the middle east. Even going so far as having himself crucified on an oak "Tree" while wearing a Crown of Hawthorns.
Radical Druid Paganism was not something we would normally expect in the Palestinian Provinces 2,000 years ago.

Orbital capture. It's more than two. A lot more -- try 48 known headed by the four major retrograde moons: Aneke, Carme, Pasiphae, and Sinope.

Well, I can't.... but I bet Stephen Hawking could.

Jupiter has more than two moons...
Here is a good site that explains things in simple terms for you;
http://solarsystem.nasa.gov/planets/profile.cfm?Object=Jupiter&Display=Moons
Basically, they are so tiny that they are, in all likelyhood, "captured" objects. That is to say, asteroids or microids that were floating around and were captured in Jupiter's gravity well.
No need for a magic sky pixie at all. See?

Not at the moment, but I am sure I can Google it and come up with an answer for you lickety split. ;)
While I am doing that, do you think you can dig up some solid, scientific, empirical proof that God exists?
Let's see who gets back first.

Likely they were formed at different times.
hunks of rock attracted by Jupiter's gravity. entering the gravity fields at different angles or direction

good job at making christians look retarded. science doesn't cease to exist with the acceptance of God's existence, they compliment each other.
