do you think there is another planet like earth?

I had read a shocking science fact. The number of stars in the sky, which are known to us, has outnumbered the number of sands on Earth. Besides, stars are like our sun, and there aer even larger number of planets surrounding all these stars (similar to our solar system). So, like buying lotteries, don't you think there are chances that one of the stars having a planet similir to Earth (we are one of them). It might not be exactly the same, but no doubt it has similar atmosphere, having civilization and many other creatures and plants. Discoveries and technology advance leads to enlightenment. One day later, our descendents will know that we are not alone in the universe. It's just like people from the medival age thought that Earth is the center of universe. It's proven to be wrong later on.
