With the Artemis Moon Mission begins a new chapter for human beinglife/for humanity.

One of the goal is to build a permanent base ion moon, on exactly in the South pole, where there is the possibilitiesy to find water.

Can’t build a base inside of the moon, therefore use on

Is -> singular
Are -> plural

You talk of one, therefore ‘is the possibility to find water’, however we would also use ‘possibility’ in this sentence; ‘there is the possibility to find water and aliens’, if you would like more examples let me know

In some moment inthe future, if all goes well, we will birth a create the first human on the Moon.

This baby,human shall become the first native from/on the moon.

And I have a question, in case/query, if this baby happened to visit the earth, we could say which he ishe be an alien?

The earth -> dirt, soil.
Earth -> noun, the name of the planet we live on

Remember to reverse word order if it’s a question

Would is used here, as you are talking about a hypothetical situation. <<< i have picked this up a few times in your writing i believe, if you want to improve, i would highly recommend a post focusing on a few sentences containing this concept, would be happy to mark
