Why is the Earth a special planet in the solar system?

This question relates to creatures living on our planet. For us, the Earth is truly unique. Because we cannot live except on planet Earth. Here we have all the conditions for life. Water, sun and oxygen. Perhaps on other planets there is life and the creatures of these planets + 500 degrees Celsius is normal temperature. Perhaps we ourselves are inside the being, like microbes in our body. All this is relative and, in principle, there is no evidence that we are only one intelligent creatures in the solar system. I think we will never find out about this.
