at present the theory is that all of the planets that make up the solar system were formed at the same time when the Solar System condensed out of a cloud of gas about 4.5-4.7 billion years ago.

Where is the earth came from?

When the solar system was being formed, some rock and dust and stuff like that collected in the young sun's orbit, thus creating the planets. There were many planets at first, but many of them destroyed each other. A mars sized planet smashed into the young Earth, and the debris from the collision created the Moon. The Earth cooled, and scientists think that comets from water to Earth. And the rest is history =P

Was Venus and Earth formed about the same time?

this depends on what theory you believe if you are religious or not even if god made the earth then I'm guessing that earth came first but with the big bang they could have possibly been created together but if the atoms crashed then it would have expanded out from there so then they wouldn't have. This is purely belief orientated According to science books, Venus formed first because it is bigger, and absorbed everything within its orbit to make a bigger planet and when other planets formed they did the same thing but since Venus took up a lot of the objects in space already, the planets formed afterward only had so much to grab and pull into its orbit and become bigger.

What came first the moon or earth?

We're not exactly sure, but it seems most likely that the moon was formed early in the Earth's history, when a large body collided with the Earth, shearing off molten debris. This molten debris formed the Moon. Most research and models show that the moon formed either at the same time or shortly after the Earth.
