Jew Speaking, not atheist or Christian. I will give you long answers that are directly from religious books, if you read it good for you. If not I understand; they're long.
Man was created not only for the purpose of expressing unity with G-d in his own life; he was also given the potential to suffuse the entire world with an awareness of G-d's unity. Adam, the first man, gave expression to this potential on the first day of his existence by addressing all of creation:[10] "Come, let us bow down; let us bend the knee before G-d our Maker."[11]
By imparting his superior relationship with G-d to the entire world, man becomes G-d's partner in creation[12] and contributes a necessary element to the world's existence - a conscious union with G-d. This uniquely human perception of G-d's pervasive unity makes Rosh HaShanah, the day of man's creation, eclipse the 25th of Elul, for the potential for oneness with G-d that came into being with man's creation overshadowed all previous levels of creation.
In other words, nothing can recognize its self.
Clearly, this level of prayer that is totally dedicated to G-d and not for our own desires is one that is not easily achieved. However, we certainly can gather from the concept behind it the significance of selflessness. Thinking of the needs of other people and not just our own is the first step we can take to achieve this lofty goal. Indeed, some interpret that the reason that the commandment of loving a fellow-Jew as yourself is such a central pillar of Judaism (see Rashi to Vayikra 19:18 from Sifrei quoting R. Akiva) is that through recognizing the needs of others, we arrive at a fuller, more heightened awareness that we are not the center of the world. Ultimately, we become fully cognizant of the fact that G-d created the entire cosmos to allow Man to elevate his quintessential, spiritual nature by drawing nearer to Him, the true center of the universe.
To recognize inside ourselves the oneness of the entire world and our God and creator
4. If angels do not have free will, how did some rebel?
Most of this is ancient mythos, added into Christianity.
Supposedly the Nephillim were fallen angels, but I don't understand that at all.
Whilst sitting one day in the presence of Rabbi Simeon, this question was asked by Rabbi Isaac: "What impelled these Postdiluvians to be so foolish as to revolt against the Holy One, and how did they become actuated with the idea of building a tower whose top should reach unto heaven?"
Said Rabbi Simeon: "We learn from tradition that by the words, 'and it came to pass as they journeyed from the east' (miquidem) scripture informs us that they quitted the highlands for the plains, the land of Israel, in order to fix their habitation in Babel. 'Here,' said they, 'we can live and dwell, come let us make to ourselves a name, or in other words, let us worship and adore the god of this world, and by so doing acquire and enjoy his favor and help; so that when catastrophes and calamities occur, we shall have here a sure refuge and means of escape from their baneful and destructive effects. Here is abundance of food, and we may reap plentiful harvests which in the past have cost us so great toil and labor. Nay, more, let us make a tower reaching up to heaven, so that we may mount and wage war in the domain of the Premier himself, and thus prevent him from again overwhelming and destroying mankind with a deluge, as in the past.' It is written, 'And the Lord said the people is one and they have all one language and this they begin to do, and now nothing will be restrained from them which they have imagined to do' (Gen. XI. 6). The meaning of which words this is. In the celestial world when all its spheres are harmonious, power is the result. So is it in the world of mankind when all minds become imbued and swayed by unity of thought and feeling. Whatever enterprise or project is undertaken, it is bound to succeed and be accomplished whether its object be good or evil. To nullify their impious intention and purpose of waging war against it was essential that this unity of design should be broken and their plans be thwarted and, therefore, as stated, 'The Lord scattered these

builders of Babel and dispersed them abroad upon the face75b-76a of the earth. And that they might be compelled to cease the building of their city, he confounded their language so that they were unable to understand each other's thoughts and respond to them. Before this the holy language was universally spoken.
