说起人类的起源，就不得不提起世界三大起源学说：海猿说、海陆双祖先复合说与外星人说。它们各有各的观点，也各有各的证据，真是众说纷纭，莫衷一是。

When it comes to the origin of human beings, we have to mention three theories of the origin of the world: the theory of sea ape, the theory of the combination of sea and land ancestors and the theory of aliens. They have their own opinions and evidences. They have different opinions and opinions.

对此，北大西洋公约组织的科学家马莱斯认为：大约65万年前，一些外星人来到地球，他们具有高度的智慧和丰富的科技知识，发现了地球上的环境很适应他们居住，但他们却不堪忍受地心引力的作用，于是这些外星人不得不放弃地球生活，并决定在地球上创造出一种新的适宜于在地球上生活的人种，同时又使他们能在地球上繁衍。他们选择了地球上精力旺盛、智力较高的雌性猿人作为对象，设法使他们受孕，这便产生了我们人类的祖先。

To this end, Malis, a scientist of the North Atlantic Treaty Organization, believes that: About 650000 years ago, some extraterrestrials came to the earth, they had a high degree of intelligence and rich scientific and technological knowledge, found that the environment on the earth was very suitable for them to live, but they could not bear the role of gravity, so these extraterrestrials had to give up life on the earth and decided to create A new kind of people suitable for living on the earth, at the same time, they can reproduce on the earth. They chose the energetic and intelligent female ape man on the earth as the object and tried to make them pregnant, which produced our ancestors.

马莱斯的见解的确惊世骇俗，但我不同意这种说法，假如外星人真的来过地球，真的与猿繁衍出新猿，那么在这400万年中，难道会一点痕迹都没有吗？如果地球人真的起源于外星人，那么发现了30万年前、40万年前乃至100万～200万年前的古代类人猿化石又如何解释？虽然总有所谓的“ufo”出现在地球的上空，刺激着我们的眼球，可又有谁见过外星人呢？

Marley's opinion is really shocking, but I don't agree with that. If aliens really came to the earth and really bred new apes with apes, wouldn't there be any trace in the four million years? If human beings on earth really originated from aliens, how can we explain the discovery of ancient anthropoid fossils 300000 years ago, 400000 years ago and even 1-2 million years ago? Although the so-called "UFO" always appears in the sky over the earth, stimulating our eyes, who has ever seen an alien?

我比较赞同的是海猿说。1960年，英国的人类学家阿利斯特·哈代提出：在化石空白期，人类的祖先不是生活在陆地上，而是生活在海洋中。

I am more in favor of the sea ape. In 1960, British anthropologist Alister Hardy proposed that in the fossil blank period, human ancestors did not live on land, but in the sea.
