You have nothing to defend. You are nothing. We are all nothing. God is nothing. We are all god.
Humans are nothing.
God is nothing.
Nothing is nothing.
So humans are God.
Your statements essentially boil down to:
Nothing is nothing is nothing is nothing is nothing.
It's meaningless.
It does nothing to address the reality that we are here, living on a beautifully designed earth in a vast jaw-droppingly amazing universe designed by an even more amazing God who gave us consciences to know right from wrong.
It doesn't address our lives on any relevant level. It doesn't answer questions about why we are here or where we came from or where we are going or what the purpose of life is.
The implication seems to be that there is no meaning to anything, no purpose to anything, no value in anything, that human life and behavior is irrelevant.
This philosophy stems from evolutionistic thinking, that existence is an accident, and we are nothing more than particles in motion.
However, reality and fact strike down such absurd ideas.
Beginning with your own statement about rape being wrong, you've disproved your meaninglessness argument on your own. You can't have come up with a "rape is wrong" argument on the basis of a meaninglessness existence.
You know rape is wrong because God put His law in our hearts. We know right from wrong, we know the reality of good and evil.
The fact that our consciences prick us in accordance with the same rules God's written out in Scripture is good evidence that the source of our consciences is this very God who articulated His law in His Word.
God says we are without excuse.
Romans 1
18 The wrath of God is being revealed from heaven against all the godlessness and wickedness of people, who suppress the truth by their wickedness, 19 since what may be known about God is plain to them, because God has made it plain to them. 20 For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that people are without excuse.
21 For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened. 22 Although they claimed to be wise, they became fools 23 and exchanged the glory of the immortal God for images made to look like a mortal human being and birds and animals and reptiles.
24 Therefore God gave them over in the sinful desires of their hearts to sexual impurity for the degrading of their bodies with one another. 25 They exchanged the truth about God for a lie, and worshiped and served created things rather than the Creator—who is forever praised. Amen.
26 Because of this, God gave them over to shameful lusts. Even their women exchanged natural sexual relations for unnatural ones. 27 In the same way the men also abandoned natural relations with women and were inflamed with lust for one another. Men committed shameful acts with other men, and received in themselves the due penalty for their error.
28 Furthermore, just as they did not think it worthwhile to retain the knowledge of God, so God gave them over to a depraved mind, so that they do what ought not to be done. 29 They have become filled with every kind of wickedness, evil, greed and depravity. They are full of envy, murder, strife, deceit and malice. They are gossips, 30 slanderers, God-haters, insolent, arrogant and boastful; they invent ways of doing evil; they disobey their parents; 31 they have no understanding, no fidelity, no love, no mercy. 32 Although they know God’s righteous decree that those who do such things deserve death, they not only continue to do these very things but also approve of those who practice them.
