our planet like any other, is made just about the same stuff from space. then, my question is: why should we go to the moon and mars to bring more stuff?
don´t we have the same here on earth?
were the rocks from the moon different?
if so, why?
why aren´t the rocks similar ?
thanks for your answers and greetings from México!

The rocks on the moon are very similar in composition to the rocks found here on earth. In so much as the most popular theory based on evidence is that the moon was once part of the earth but because a large object stuck earth about 4.6 billion years ago it knocked off enough material from earth to form our moon. We go to Mars and the moon so we can analyze differences between planets and to possibly find life somewhere else in the universe. If we are to survive as a species we will eventually have to relocate to another planet. I hope this helps.

The rocks brought back from the moon were similar to the material in Earth's mantle (not the crust) helping prove the theory that the moon was formed by a massive collision of a large object with Earth while it was still forming 4 billion years ago.
The basic rocks of Mars may be similar to Earth, but Mars has had a different climate and different meteor/asteroid impacts, different effects due to a reduced magnetic field, etc. It may have water, it may have life - so that's worth investigating.
Think of it this way. Hardboiled eggs and an omelet are both made of the same original raw material, but they are very different end results.

Yes and no.
The atoms and molecules are the same stuff - Yes.
But the ratios we find them in answer questions about the formation of the solar system and the moon, and conditions in space, both now and in the past.

BEBE, anything brought from outside the globe is extraterrestrial and needs experimentation for that planet's age, its water content, mineral, phosphur etc. we learn a lot from the findings.

well i guess it is but they just want to see what they will find because it does not have the same atmosphere so in other words it is a little diffrent cuz the particles are arranged diffrently
