If there really was a big bang, why are planets near perfect in size. I mean if it was a giant explosion, wouldn't the planets be in different shapes and sizes. Why isn't there a planet in like the shape of an asteriod or such?

When you get enough mass together in one place, gravity forces it to even out into as close to a sphere as it can get. Only the smallest solid bodies (say, 500 miles or less in diameter) have insufficient mass to do this, so their shape is irregular.
Most planets are different sizes. They range from Mercury, which is barely bigger than our moon, to Jupiter, which is more massive than the rest of the planets in our solar system combined
What do you even mean?
Yes, planets are round (well, obviously, they aren't perfect spheres, but I suppose that this fact is kind of beside the point at the moment). And do you know why they are round? Have you ever hear of this thing called gravity? It's a fairly recent discovery. Isaac Newton only figured it out a few hundred years ago, so I understand if your not entirely up to date on it.
And, there are these asteroid-shaped things that orbit stars. They are called asteroids. Asteroids are typically smaller than planets . . . which might possibly why they typically aren't as spherical ( I think it kind of has something to do with that novel concept of "gravity" I mentioned earlier).
All of the above.
And they claim they don't idolize people

Hey Steven, there's a drunk knight at the door with a big sledgehammer asking for you; looks really, REALLY pissed off. Says his name is Isaac and he has a quarrel to settle with you.

They are and there is.
Any questions?
First, planets can differ greatly in size,
and second: The planets didn't come into existence at the big bang. They came into existence millions of years later, by a completely different effect (gravitational aggregation)
Because a sphere is - demonstrably - the shape that holds a given volume in the tightest surface and shortest distance from the center. Therefore, mass pulled together by gravity tends to shape itself as a sphere. This is partially countered by rotation, so that planets are actually fatter at the equator than a perfect sphere. For example, the radius of the Earth at the Equator is 6378.1 km, while the distance between the poles is only 6356.8 km.
Obviously, S-22 has studied the planets, and I mean all of them, and found them nearly identical. And all perfectly round, with only one day to round off after the bang, 6,000 years ago.
Confused?
