The solar system

It's quite puzzling as to why it has become like that. Despite being in the same solar system, the nine planets developed differently. Space has so many particles that one thing can become entirely different despite being in the same area.

The earth gets the right amount of sunlight which has been the main source of energy for the growth of plants and animals and hence life originated and has sustained over the years on earth.

The Earth is strategically placed compared to the other planets. It is neither too close to the Sun nor too far from it. Hence it receives the right amount of light and heat from the Sun to sustain life on Earth.
