Why I 'M Descartes' Lack Of Knowledge?

Saturday is a day I try to spend in the nature’s company. I like the cool breeze when the day is sunny and warm. I looked at the sky. It seemed so blue and so close, and just by climbing the little hill in front of me, it seemed I could reach the sun, which looked no bigger than the ring on my hand. After a few hours of walking over the hill, the sun seemed to be the same distance from me, and it was the same size, just like the moon that soon replaced it, surrounded by thousands of little stars. I enjoyed the nature around me that looked so perfect, just like God who created it. That made me think. What if those little stars were not so little in reality, or what if the sun or moon was larger than it seemed to me? What if the sky is not blue, but my eyes perceive that color? Why would God deceive me that way? He has infinite knowledge and judgment, and it is no surprise that I cannot understand all the reasons for making error and not seeing the truth. I am just a human being prone to errors. I cannot see the truth because of my limited knowledge, and my lack of judgment. Why then, God who is perfect, have not given me unlimited scope of knowledge or will that helps
His argument that God cannot create an error because he is good, and that he is source of all good, is undoubtedly a weak one. He also fails to see possibility that God may not have created everything that exists, and that evil could play a big role in it. It seems to me that all positive and good comes from God, but evil comes from us. Additionally, he is convinced that God exists because he can clearly and distinctly perceive that idea, but he can trust his clear and distinct idea because he knows that God exists. In conclusion, Descartes arguments seem very convincing at first, but after detailed analysis, it still remains unclear, which leaves problem of error
