请帮我翻译一下这段英文 20分奉上

宇宙是无限大的，地球只是其中的很小一部分。既然地球能存在生命，为什么其他星球不能有新的种族？也许他们有一部分几经拥有了空间旅行的能力，到达地球。他们或许还不了解人类，因此不想直接和我们沟通，因此我们很那发现UFO和外星人的存在。 请不要用网页翻译。语法好多都是错误的。谢谢

The universe is infinite and the Earth is only a minute part of it. If there can be life on Earth, why can't other planets have new species ? Perhaps some of them already possess the ability of space travel and have reached the Earth. They may not have understood human beings so they do not want to communicate with us directly. That is why it is so hard for us to discover the existence of unidentified flying objects (UFO) and extraterrestrials (aliens).

The universe is infinite, and the Earth is only one small part of it. Since life on Earth can exist, why not other planets have a new race? Maybe some of them have had the ability to travel in space, to reach the Earth. Perhaps they do not know the human being, so they do not want to communicate with us directly, therefore we hardly find the existence of UFOs and extraterrestrials.

The universe is infinitely big, the earth is only a very small part of it. Since the earth could exist living creatures, why does other planet have new race？Maybe some of them have the ability of space traveling to reach the earth. And perhaps they do not know human and don't want to communicate with us directly, so we have difficulty to find the existence of UFO and extraterrestrial being (ET).

The universe is infinite, and the Earth is only one small part of. Since the existence of life on Earth can be, why can not other planets have a new race? Maybe they have some space several times the ability to travel, to reach the Earth. Perhaps they do not know the man, so do not want to communicate with us directly, so we are then found to UFO and extraterrestrial existence. Please do not use Web Page Translation. Syntax many of which were wrong.

The universe is infinite, and the Earth is only one small part of it. Since life can exist on earth, why it can not be on other plants? Maybe some of them have gained the power of traveling through the space to reach the Earth, or maybe they do not know much about human beings, so they do not want to contact with us. That's why it's hard for us to find UFOs or aliens.
