The earth is supplied with energy from the sun at a proper distance and keeps its temperature such that all living things can exist here. Other planets are too far way from the sun or too close to sun, so they have extreme temperatures and nothing can live there. These things have been observed with large telescopes. Moreover, when we observe atomic size particles which are elaborately formed and move in similar perfect order, we cannot help having reverential fear for nature and acknowledging God the Creator.
"For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made" (Romans 1:20).
