Hi IG
Let me tell you what I believe, perhaps you will like that
Human (Not human body) is the crown of all species on this earth. But, I exclude human body from the group of this crown species because acquiring human body simply just NOT make one a human. There are human out there in this world who still behave like animals. Such humans does NOT hold the right to call them as humans, even when they acquire human body. Such humans look like humans, but, they truly are animals in the costume (Body) of a human.
Of course, there's something that makes a human different from animals. And that's definitely is NOT based on any materialistic/scientific prosperity which has been made by us till now. The word "Human" is quiet very old. Its even more older when the first electric bulb was discovered.
I also believe in reincarnation. I believe that animal soul become capable of human body after a lot of improvement. This improvement perhaps may take many rebirths. Yes, animals also learn from humans so that their soul could get improvement and they become capable of human body.
Animal becoming capable of human body simply doesn't make that animal a human in true terms. Human and Animal are two different words and of course there a point from where the human journey starts. But, before that animal in a human body is no more than a animal.
Question is.. what point is that, thereafter one is said to be a true human ?
My answer is.. Right from the moment when any soul start thinking upon.. "What is the purpose of life" or "Who am I" or "Why am I" or any such question / idea.
If any such question comes into one's mind ?
I congratulate that person because that's the point from where the journey of a true human-being starts
