8) Solar eclipses get all the attention, but if you are able to catch a glimpse of a lunar eclipse, you can see evidence that the Earth is, indeed, round. Here's how it works: Earth passes between the moon and sun, so that the sun projects Earth’s shadow onto the Moon in the night sky. You've probably seen a partial lunar eclipse without even noticing it; if the moon looks orange, that's a sign of a lunar eclipse. If you've ever seen a total lunar eclipse, you probably noticed that the shadow did not look like this.
9)The generation of life in our planet was also caused due to the preferable atmosphere of our planet. Our atmosphere contains different gases, including the oxygen which is necessary for our respiration. The presence of these gases made our planet livable for ourselves
