Why not immigrate to the moon instead of to Mars?

The exploration of outer space is confidential, and the United States can't be stupid enough to openly ask weakly, how do you know that the United States is focusing on Mars instead of developing the moon? The founding brother said it himself?

Many people always think subjectively according to their own cognition. You know that in the past 100 years, the United States has explored the moon countless times. As the closest planet to the earth, do you think the United States will give up exploring or developing the moon? The reason why human beings have been exploring outer space is mainly to find some planets suitable for human habitation, except similar ones. Although the moon is closest to the earth, it is not suitable for human habitation. On the other hand, although Mars is far away from the earth, it is likely that life once existed. More importantly, there are many resources on Mars.

Not the Milky Way, just the solar system. Besides the earth, Mars may be the last place where life once existed. Do I need to tell you why America is concerned about Mars? If other species or life are found, then the United States will definitely want to be the first to contact. If Mars is found to be suitable for human habitation, then the United States will be the first country to occupy it there. I hope everyone will not forget that the United States is an immigrant country and how the United States treats local aborigines.

So, it's not that I don't want to develop the moon, but that there is nothing worth developing on the moon. The previous exploration has already had a basic understanding of the moon, and the resources on the moon have also been proved, which has accumulated enough experience for the future Ad Astra. Moreover, the spacecraft developed by the United States is enough to support the exploration of further planets. It's normal to try to explore, and the United States is not only interested in Mars, but also actively exploring other planets, okay? So, you may not want to explore the moon because you know some inside information, but the reason why you continue to explore Mars is related to the ultimate goal of our space exploration. As for what purpose, think for yourself.
