Are God and Satan the same or the Bible has been corrupted? Can't you answer my question? Is it hard

Yes, you are right. Allah says in Quran:"Allah is the Light of the heavens and the earth. 24:35" But we must know why Allah has told so. We are unable to know Allah. We cannot describe him. We just can describe Allah as He has described Himself. If you read Quran, you will find out that Allah gives us some examples which help us to understand easily: " If We had sent down this Quran upon a mountain, you would have seen it humbled and coming apart from fear of Allah. And these examples We present to the people that perhaps they will give thought. 59:21" "And We have certainly presented to the people in this Quran from every [kind of] example. But, [O Muhammad], if you should bring them a sign, the disbelievers will surely say, "You [believers] are but falsifiers." 30:58 Ok, Allah says He is the light of earth and the heavens. It is just an example. Let me explain more: When there is light, we can see everything around us clearly. And when it is dark, we can see nothing. In another word, when we can see something, we find out that light exists. Allah is the light of earth and heavens. Do you know why? It means, when we look at a creature (like a flower), we realize that Someone has created it. When we look at everything, we will find out that a Creator exists. There is another reason; everything requires light for being seen. The example of Allah's existence is similar to light. Because everything needs Allah to live. We can't do nothing without Allah's help. You said:""Could he not have then said "be" intending man know good and evil without the existence of Satan?" Allah could do this. But you must know that if Satan didn't exist, there would not be evil in the world. Satan is the source of all kind of evil. If Satan didn't exist, life would make no sense. Everybody would be the best person. Everybody would do good deeds. And as a result, all people would be the same. But now, people are different. You can see some people who are more religious than you. You also can find some people who are more sinful than you. Satan helps us to find the best people. Allah could make all of us perfect. He could force us to obey Him. But he didn't. If he did so, what would be the different between us and animals? As we know, animals cannot decide or think. They just follow their nature. But Allah granted us intellect. He grants us the ability to think or decide. He wants us to choose our own way. He wants us to choose our destination. He tells us what will happen if we follow Satan: "Indeed, Satan is an enemy to you; so take him as an enemy. He only invites his party to be among the companions of the Blaze. 35:6" He also shows the Straight Path: "And Allah invites to the Home of Peace and guides whom He wills to a straight path. 10:25" Allah lets us choose whom to follow. In Quran, he warns us of following Satan and gives us glad tidings of rewards for following Him. Ok, I think I should tell you more about Satan. He was the best worshipper of Allah. He had worshipped God for more than 6000 years. Read the following story, please: On the night of Mi'raj, Prophet Muhammad (peace be upon him) went to the heavens and sighted every spot there and the same night returned back. In the morning of that night, the Satan visited the Prophet and said:" O Messenger of Allah. Last night you went to Mi'raj and on the left of the fourth heaven you observed a pulpit, which was broken, burnt and toppled. Did you recognised to whom belonged that pulpit?" The Prophet replied:" No," Whose pulpit was that?" The Satan replied: "It is my pulpit which belonged to me. I was sitting upon it and the angels were sitting before it and I was >talking about the devotion towards Allah. The angel were amazed of my worship to Allah. When ever my rosary was falling down on the ground many thousand angels were getting up in a hurry to kiss the rosary and giving it back to me. I was believing that Allah did not created better creature than me. But once it happened against my wish and I was thrown away from the doorway of Allah and now nobody is worst and cursed than me in the presence of the One Allah. O Muhammad! Do not be proud and never show haughtiness as no body can realize about the acts and affairs of Allah." In his visit to prophet John (a.s), Satan said:" I was among the Archangels and for four thousand years I did not raised my head from a single prostration but my consequence was such that I was thrown away from the rank of archangels and became cursed and excommunicated from the threshold of the Almighty Allah." Now, I want to tell you about the disobedient of Satan in Quran: "[So mention] when your Lord said to the angels, "Indeed. I am going to create a human being from clay. So when I have proportioned him and breathed into him of My [created] soul, then fall down to him in prostration." So the angels prostrated - all of them entirely. Except Iblees; he was arrogant and became among the disbelievers. [Allah] said, "O Iblees, what prevented you from prostrating to that which I created with My hands? Were you arrogant [then], or were you [already] among the haughty?" He said, "I am better than him. You created me from fire and created him from clay." [Allah] said, "Then get out of Paradise, for indeed, you are expelled. And indeed, upon you is My curse until the Day of Recompense." He said, "My Lord, then reprieve me until the Day they are resurrected." [Allah] said, "So indeed, you are of those reprieved Until the Day of the time well-known." [Iblees] said, "By your might, I will surely mislead them all Except, among them, Your chosen servants." [Allah] said, "The truth [is My oath], and the truth I say - [That] I will surely fill Hell with you and those of them that follow you all together." (Quran 38:71-86)
