For the millionth time: evolution by natural selection is not about luck or chance. As the name suggests, it's about selection.

Perfect? We and our world are far from perfect. Our pelvises aren't completely rotated causing humans to have lowr back pain, we have toes that we don't need, our appendices are useless and get infected frequently, our knees are flawed and put too much stress on the tendons, so much so we have to grow an extra bone (kneecap) to protect it, the evolution of plant life caused the oxygen to be here and the atmosphere was once so rich with it that lighting caused massive explosions, we filter and sanitize our water and cook our food. We live on a beautiful planet that has a system of life that only barely works. There may be life on other planets, in our own dolar sstem even, but our definition of life is so narrow that a virus's life is hotly debated. Its not luck, but it really only barely works. If the planet was so perfect, why did we build stairs and sidewalks?

You're looking at the situation backwards. Life adapts to the current environment. So on the bottom of the ocean, life adapts to high levels of pressure and toxic chemicals. If there is no "food" live adapts as a plant or something that can use minerals or light for engry.
As of yet, we have not even began to identify a tiny fraction of all the possible planet in our galaxy much less the remaining universe. Until we know all of the planet in our galaxy, how can we with any confidence say that life only exists here?

We evolved and adapted to the conditions. It is not perfect. Think of things like sickle cell anemia, an adaptation that helps people not contract malaria but those who have it are also weakened by the change in the shape of their red blood cells. Scientists believe that there have been several species of humans but we are the only survivors, from their perspective evolution wasn't so perfect. Through the planets history many species have been wiped out when conditions changed and they could not adapt. Was evolution perfect for them?
As for other planets, what we know of our own solar system is minuscule. What we know about the galaxies that lie beyond our own in the vast universe is practically nil.

Evolution is in fact self-explanatory. Evolution means that organisms fit for survival will survive.
You have the wrong perspective. The question "why is there food for you to eat" is wrong. The species on earth adapt to their surroundings and will eat (and enjoy) whatever is there. It's not only pure luck, it is logical adaptation to the surroundings. There are only two possibilities: either you eat what's there, or you starve. Therefore the species which ate were the ones which survived. And for them, the world was perfect (well, as perfect as it gets).

Given all the planets in the universe, it is inevitable that one will have the perfect conditions for life. Obviously, once life starts on this planet, it will thrive and evolve for many years, because the conditions allow this. Earth was one of these planets. It wasn't luck, it was inevitable that at least a few planets would end up this way, given all the planets out there. Humans assume it was created because they say "the earth is perfect for life, but other planets aren't." If Mars was perfect for life, and earth wasn't, then we would be saying the same thing, but about Mars.

why do you think that evolution and GOD are mutually exclusive? evolution may just be a fundamental part of GOD's process of adaptation and survival of the various species that GOD alone created. perhaps you should answer the question of whether or not the chicken or the egg came first?
without GOD creating the planet and all the species how could there exist anything which can evolve.

You call what we ended up with perfect?????? I mean why is your breathing tube and your throat together so that you can choke? Why is the optic nerve on the front side so you have a blind spot? Why do you have inner eyelids that don't work? Why do you have an appendix?
Those things you list are simple. If they weren't there the line would have died off and evolution would have gone a different direction. There is no luck involved at all.

Don't get me started on Evolution. Even Darwin didn't fully believe his theory. If evolution is soo perfect, why did Hitler kill all those ppl for it. If natural selection is so great, why did the American Birth Control League (aka Planned Parenthood) try to stop those they thought didn't deserve to have children by means of sterilization.
Pure luck would be me winning the lottery 5 x's

You are looking at only the first century in mankind's history when a person can life a full life without fear of famine. Your "perfection" is a result of technology. Most of the history of mankind has been a great struggle. This solar system has only one planet that supports life. We don't even know how many Earth-like planets there are in this galaxy, much less the universe. Your question is quite myopic.
