Our solar system for example is constructed in just the right way to allow life to exist on this Earth. Take away any small part of it and conditions for life would be negligible.

That's a logical fallacy....... an appeal to ignorance. Sounds like something out of a Lee Strobel book.

The conditions on earth at this moment are capable of sustaining human life but there was a time when the O2 levels would not have and it is likely that there will be a change in the chemical signature of the atmosphere to inhibit human life again but other forms of life will continue to thrive.

As there have been chemical changes on earth so are there changes on other planets in the universe to promote life so it is just patently wrong to assert that our solar system is exceptional against a universe undergoing constant change.
