What is the major difference between man and the Apes on earth?

 The main difference is that we can speak languages and use tools better than they can.

So, the likelihood is that speaking came from other planets as beings from other planets interbred with us or genetically engineered us from their genetic makeup and created us from disease resistant Ape genes and their genes from other worlds to create us who could survive here as a species and we have for likely 65 million years.

However, what I don't understand fully is what entirely happened the last 65 million years because of all the Ice Ages a lot of Humanoids (our ancestors) likely left on space ships because life would be pretty daunting many places on earth except nearer the equator during Ice Ages.

However, we also have esquimos, or native Americans or native Greenlanders or northern people's of Europe and Siberia that also found ways to survive ice and cold too. So, where there's a will there's a way when people are determined enough to survive anywhere on earth or in the earth in caves that are natural or that they dig. So, there are many ways to survive here on earth.

It never ceases to amaze me the ways that human being find to survive here on earth, especially in plaees like India and Nepal when I visited there in 1985 and 1986 with my family then. We stayed from December of 1985 to April of 1986 then before we returned to San Francisco, in California then.
