I think therefore I exist

I heard it said that's the difference between human being and animals is that human being are able to think! will that means animals do not think? I totally disagree, I have seen animal think and reason to conclusions, this I have learned from my first dog Scruffy when she was a puppy , she was not allowed to get inside the house, being a puppy she couldn't stay by herself for a short while, so she was sitting on her mattress on the terrasse, when I walked in the living room to go to the kitchen, it was time to prepare dinner, she put her head at the door and cried after me, I said scruffy stay! I will be back soon, got busy with the cooking when I heard her making that particular sound umumum, I turned my head to find her sitting on the steps outside the kitchen door sticking her head in to watch me cooking. that made me think, she saw me coming in one door. How did she came to the though come all the way to search for the kitchen door?
and she has figured out how to be with me without breaking the rule, that was a two month old puppy, so who say animals don't think? what Scruffy did was thinking a way to get her what she wants, with out being punished.
I don't know when children start think, but I know that I still remember one thought, when I was just three years old, it was evening, my father sitting on the edge of the pond in the garden
putting me in his lap, the sky was brilliant and full of bright stars, the sky deep blue light pollution was not existing at that time in history!! my father had a great idea that his little daughter is able to understand every thing, so started to point with his finger to the stars and
telling me this is called Vinous and this is the Orion belts this is the big dipper , I didn't understand, any thing of that I couldn't see where his finger was pointing. For me they where stars, beautiful stars, the trees in the garden were big and great, and I am sitting in my fathers lap having him all for myself, it was a great moment for me, I was thinking, God is great he created all of those wonderful trees and those bright stars!! this is my memory not that any one told it to me, because I know I didn't say a word , didn't have the language to express it, it was just a thought!!??!!
