The Renaissance philosopher, Rene Descartes became famous for his quote, "Cogito ergo sum," translated as 'I think, therefore I am.' He stated that the simplest and surest way to prove existence is by the existence of thought. Is this true?
When you are talking/chatting/texting someone, occasionally one of you might ask, "what's on your mind?" Most of the time we respond "Nothing much, what about you?" Which can be loosely translated as "None of your stinking business nosey. Why don't you go take a long walk off a short peer?" Of course this is a false statement! Nothing is never on your mind, in other words, something is always on your mind. We are aware of this and therefore would tend to agree with Descartes somewhat. Yes, we think, yes we know we are real because we think. But is it the best way to prove we exist?
Blaise Pascal, a fellow Renaissance thinker, said plainly "It is odd that we cannot define these things without making them obscure; we talk about them all the time." The more we think about these things and probe them for solutions, the more difficult we are making them to understand. The answer is plain and simple, much more so than Descartes' "Cogito ergo sum."
This answer can be found in Genesis 1:28-31,
"And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth. So God created man in his [own] image, in the image of God created he him; male and female created he them. And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth. And God said, Behold, I have given you every herb bearing seed, which [is] upon the face of all the earth, and every tree, in the which [is] the fruit of a tree yielding seed; to you it shall be for meat. And to every beast of the earth, and to every fowl of the air, and to every thing that creepeth upon the earth, wherein [there is] life, [I have given] every green herb for meat: and it was so. And God saw every thing that he had made, and, behold, [it was] very good. And the evening and the morning were the sixth day.
God created us. We exist. How do I know? God said so, plain and simple. End of story.
