What I believe is, that from the time there have been men advanced enough to worship, they have reached out for the God they instinctively knew was there.
(instinct-built in?)
God had revealed Himself "from the beginning"...but as time passed and people spread out, what was once known as a universal truth faded into ancient myths...
But, as I said, there is an instinct...a longing for God. People reached out for Him, reinventing Him over and over again...
Eventually, God made His voice heard again. He called a man named Abraham, and promised him that through his son, all the families would be blessed.
And that is what the Bible is all about.
Now, while I know there are many, many, many "look-alike" gods, there really is only One Jesus Christ.
In Him, and in Him alone, do I see God reaching down to mankind. He taught us love, and peace, and charity...love your neighbor as yourself; love your enemies; give to those who ask you, good measure, pressed down and shaken together; and my favorite verse in the entire Bible, which, since you haven't read it, I will post here for you:
Joh 13:34 A new commandment I give unto you, That ye love one another; as I have loved you, that ye also love one another.
Joh 13:35 By this shall all men know that ye are my disciples, if ye have love one to another.
