Does God exist?

Psalms 14:1 The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works, there is none that doeth good.
 Psalms 53:1 The fool hath said in his heart, There is no God. Corrupt are they, and have done abominable iniquity: there is none that doeth good.
 Isaiah 44:6 Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I am the first, and I am the last; and beside me there is no God.
 Isaiah 44:8 Fear ye not, neither be afraid: have not I told thee from that time, and have declared it? ye are even my witnesses. Is there a God beside me? yea, there is no God; I know not any.
 Isaiah 45:5  I am the LORD, and there is none else, there is no God beside me: I girded thee, though thou hast not known me:
Genesis 1:1  In the beginning God created the heaven and the earth.
Acts 17:24 God that made the world and all things therein, seeing that he is Lord of heaven and earth, dwelleth not in temples made with hands; 25 Neither is worshipped with men's hands, as though he needed any thing, seeing he giveth to all life, and breath, and all things; 26 And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation; 27 That they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us: 28 For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his offspring. 29 Forasmuch then as we are the offspring of God, we ought not to think that the Godhead is like unto gold, or silver, or stone, graven by art and man's device. 30 And the times of this ignorance God winked at; but now commandeth all men every where to repent: 31 Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead.
God needs no one to prove His existence.  The creation itself proves to us that God is the creator.  Everything points to the loving Creator we see described in the scripture.  However many choose to deny the existence of the true and living God.  Faith is the means by which we must know God.  He has chosen this method which makes it possible to all.   Anyone who chooses to believe can come to know the true Creator of the Universe. Even the enemies of God are welcome at the throne of God.  The call to repent is upon all mankind.  God loves everyone no matter what we think or have done.   His love for the atheist and agnostic are just the same as for the born again believer. 
St. John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved. 18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God. 19 And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil. 20 For every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved.  21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.
