Topic: Write a paragraph of about 150-180 words about the following topic: "The advantages of space exploration"

-My paragraph :

Space exploration has done wonders for human lives. To begin with, space exploration generates scientific pieces of knowledge. By discovering the unknown, scientists have found many scientific breakthroughs that are actualizing our preconceptions and stretching our limitations about our relatively limited understanding of outer space. Second, I bet dollars to donuts that you are unaware of it, that many inventions which we are using every day were originally designed for space travel. For example, firefighting equipment, it is unexpected right? The polymers which are created for space suits have shown to be useful in the development of flame-retardant, heat-resistant suits for firemen. On top of that, when exploring space, we could even find a new home for living there in lieu of the shabby Earth - we turn it into this by littering, using pesticides,etc. We can start living in the "2nd edition Earth" without making any mistakes which we have made. Finally, it may be concluded that space exploration brings several benefits to people who are living in a convenient condition like us.
