i knpw there are, and among all those odds, we got an earth perfectly balance, by chance.
You have it backwards, Ozi. It's exactly those odds that makes life more likely. The larger the number the more chance of even a rare occurence happening and you're assuming life is rare on a sample size that is so minute it's hard to describe. It's like picking a 1"x1" square of sand in the sahara, deducing there is no life in that spot and then saying there must be no life on earth.

The axis of the earth makes a 23-degree inclination to its orbit. Seasons are formed due to this inclination. If this inclination were a little more or less than it is now, temperature differences between seasons would reach extremes and unbearably hot summers and extremely cold winters would take place on the earth.
This inclination varies and has varied hugely throughout time and life persevered through it. Again, you're assuming something that would kill our species off (a species that has existed for only the blink of an eye in geologic time), if it even would, means more than it does. Life on earth has and will survive much worse. We might not but that's just it. We are neither the "ultimate" form of life nor are we necesary to life.

Yes the earth crust varies around the globe, but any slight changes to what it is, would have an adverse affect on life.
I'm not sure what you mean here. The thickness of the earth's crust varies massively. This crust is constantly moving and is nothing like it was 30 million years ago. We've gone through upwards of 6-10 instances of supercontinenting, where all the earth's landmass has congregated in one spot, throughout earth's history. Mountain ranges come and go. Seabeds expand and shrink. Nothing about the earth's crust is constant. Luckily, it happens so slowly that life has no problem adapting to it.

The radio waves is one example, i understand that, but the point is, nowwhere else can you see a planet like ours, with 70% water, which is a substance rare in space, the right size, the right distance from the orbiting star, the right mass, atmosphere, at right proportions, an ozone layer which is perfect, and changes in that would also have adverse affect, its clear, a perfect balance.
Actually astronomers and cosmologists posit billions and billions of planets like ours and we're just developing the technology to detect them. We've been able to detect large planets for a long time but planets the size of ours are much tougher to detect.
And, again, all those "balances" you bring up didn't exist for all of earth's history. Not even it's history while life existed. You're assuming perfection because we've evolved to live in the current state of the earth. For the vast portion of earth's history most of the life evolved today would not be able to survive. That's what I mean about anthropomorphism. It seems perfectly balanced because we evolved to exist in it. But say things were totally different an yet intelligent life forms evolved. They could claim that their planet is so perfect for them that some define creator made it for them. Yet, they'd be in error. Conditions are always going to appear perfect to any life that currently exists in those conditions.
