You have a solipsistic, egocentric way of thinking (like a great portion of mankind). You believe the universe was created with you in mind. (Never mind the billions of rogue planets out there that will never bear life, never mind those worlds that will never get past the microbial stage, never the ones that only bear plant-like or animal-like life before they are pulverised in cosmic catastrophes, never mind the rare ones that hold intelligence... what is the meaning of that?)
Cosmically speaking, and this is plain to see, we are insignificant. Life has no meaning at all. If you want meaning in your life, you have to invent it. To do this, you may want to conduct yourself based on your likes and dislikes. You may devote your life to making your loved ones happy. You may live by wallowing in war with your enemies. You may dedicate your life to finding scientific answers. It all boils down to purpose. To find purpose you must answer the following question to yourself because nobody else can do it for you: What do I do next?
There is no celestial father guiding you. No Almighty with divine plans for you. If you insist on this conviction, you are yet to convince me. The universe, you pointed out, happens to have the right cosmological equilibrium that permits the emergence of life and you hold this to be enough proof of intelligent design. But the fact of the matter is, from the Big Bang, the cosmic billiards could still have stumbled upon the present conditions by chance, without the aid of a god or deity. (And if you tell me it couldn't possibly happen without a higher power, you are not a real scientist.) People win the lottery but this doesn't not mean that they were chosen. The numbers they picked just happened to be right. Furthermore, despite permitting the existence of life and consciousness, the universe is mostly too hostile and chaotic for humans and other species. Even our home planet isn't exactly hospitable with all its natural catastrophes and dangerous predators. A particular type of extremophile is known to remarkably endure the conditions of space for some time but that is about it.
So consider your argument refuted for the third time. Finally, just because there is no God with a plan for you, and just because life has no real meaning, doesn't mean that we should just blow up the planet. On the contrary! We were born in an alien world full of wonderful things yet to be discovered. And we have also grown attached to things. Enjoy life and make the most of it because at least it's something. It's not all doom and gloom for many of us. We should feel privileged that we can experience a variety of things. Lucid dreaming is great! What about sex! That's reason enough to not want to kill yourself or die just yet. There you go. All the wonderful things that surround me, and my own mind, mean a lot to me. That's my meaning.
