I see you don't understand elementary logic either. What a surprise. You cannot show that the book is true by reference solely to the claims made in the book itself. Neither is it marvellous, it's dull, repetitive, derivative, and much of it is plagiarized from Jewish and Christian sources, but that's another argument I've already had with you and I don't propose to go around it again.
Your composition will not alter the truth.
The Quran defends itself against your claims which are in fact the same as that of your ancestors.
Its similarity to the Torah and the Gospel in general outlines specially {the monotheism and the devotion to God alone} is a proof of its truthfulness, because it is coming from the same God Who revealed all the Torah, the Gospel and the Quran.
Moreover,
the Quran differs in many respects from the Torah because God revealed it to suit the specific circumstances of the Arab and the people in later generations: like the easing of fasting, the making lawful of some food items, and the less isolation of wife from husband (which for Jews was at least 14 days), while for Muslims it is about 7 days of the woman monthly cycle, and many other things like these.
Therefore,
some statements of the Torah have been changed in the Quran, and others have been preserved.
So the Jewish Abdullah son of Salam converted because he testified its similarity to the monotheism of the Torah.
Quran 46: 10, which means:
(
A witness [: Abdullah, the son of Salam] out of the Children of Israel testifies [for you] to the similarity of the [Quran teachings to the teachings of the Torah of Moses]; so [the witness] believed, whereas you waxed proud [over Our messenger]; surely, God guides not [to the way of the truth] the wrong-doing people.")
[Moroever, the Jews said to some Muslims: “Our book is better than your book, and it includes more statements and laws.” Therefore, this aya was revealed to confirm and reassure the heart of the Prophet – salam to him:]
Quran 2: 106, which means:
(
Such of the revelations [of the Torah] as We may annul [in the Quran] or preserve, We will bring [in the Quran] one better than it or one similar to it.
Don't you know that God has the power to do whatever He wills?)

To a certain extent?! The extreme conditions on other planets far exceed the extremes anywhere on Earth, to a degree that makes human life on them impossible without heroically huge investments in technology to protect them from the environment. If people were there, we'd know about it, because it could only be us who sent them there. I can indeed state for certain that there is no human life on any other planet, and it's got nothing to do with the theories of any astronomers, it's just a simple fact that nobody from Earth has landed on any of them.
You have not gone there till now, and you say this with such certainty; it is against your scientific approach. How can you assert the circumstances there are not suitable everywhere on those planets?
The nearest planet to us is Mars, and they are busy sending probes and rovers there to measure the items and bring data, then what about the more remote planets, and which are extensively large? How can you assert this, when no scientist can say this even.. but only guessing and proposing?
