KRISHNA NOT EQUAL TO CHRIST
All About Horus: An Egyptian Copy of Christ? Response to Zeitgeist movie
Question: "Are you aware that the so-called history and saying of Jesus are not authentic and were copied from the mythological stories of the different Gods of Antiquity, such as Krishna of India, Ausar, Auset, and Heru of Ancient Kemit (Egypt) which pre-dated and existed THOUSANDS of years before the so-called Jesus, and THOUSANDS of years before the Bible? I ask again, are you teaching that the Bible is Holy?"
Answer: This is not a fact and can be seen under close scrutiny. Many atheist sites utilize the scholarship that assert Jesus Christ never existed as a real, historical figure. Those who would teach such a thing are ignoring much of the historical data that is available concerning the time of Christ.
The "so-called" history and sayings of Jesus are indeed authentic and this is clearly demonstrated based on what we know about the scriptures and how they stack up against other literary works of antiquity.
The idea/theory that Jesus is not actually a historical figure, and was derived from mythical "savior-god" stories of antiquity, has been circulating among atheists for a while now. They cite the same old sources for each article/book they produce. In the case of the deities that you mention, Gerald Massey, Geoffrey Higgins and Barbara Walker are the sources that are used for the most part. There are currently (that I am aware of) NO original citations from Egyptian/Indian records/sources.
First of all, Christianity does not need any outside influences to derive any of its doctrines. All the doctrines of Christianity exists in the Old Testament where we can see the prophetic teachings of Jesus as the son of God (Zech. 12:10), born of a virgin (Isaiah 7:14), was crucified (Psalm 22), the blood atonement (Lev. 17:11), rose from the dead (Psalm 16:10), and salvation by faith (Hab. 2:4). Also, the writers of the gospels were eyewitnesses (or directed by eyewitnesses as were Mark and Luke) who accurately represented the life of Christ. So, what they did was write what Jesus taught as well as record the events of His life, death, and resurrection. In other words, they recorded history, actual events and had no need of fabrication or borrowing. 
There will undoubtedly be similarities in religious themes given the agrarian culture. Remember, an agriculturally based society, as was the people of the ancient Mediterranean area, will undoubtedly develop theological themes based upon observable events, i.e., the life, death, and seeming resurrection of life found in crops, in cattle, and in human life. It would only be natural for similar themes to unfold since they are observed in nature and since people created gods related to nature. But, any reading of the Old Testament results in observing the intrusion of God into Jewish history as is recorded in miracles and prophetic utterances. Add to that the incredible archaeological evidence verifying Old Testament cities and events and you have a document based on historical fact instead of mythical fabrication. Furthermore, it is from these Old Testament writings that the New Testament themes were developed.
In addition to the above, there are other compelling reasons to reject the notion that Christianity was simply "lifted" from pagan sources:
Those who are even a little bit familiar with ancient literature, realize that the style of myths appear wholly different from the narratives of the New Testament. The narratives in the New Testament include names, places and dates and are regarded as authentic, historical documents. There also should be an acknowledgement that skeptical/liberal scholars exist who do not simply discard the New Testament as mythology with no historical value.
The language used to describe the traits of Krishna, Horus, Osiris, Isis, etc. are misleading. One liberal scholar illustrates how biased some writers are when they describe the pagan myth in Christian language: “The dead body of Osiris floated in the Nile and he returned to life, this being accomplished by a baptism in the waters of the Nile.”
[Because of the liberal scholarship used] the alleged similarities, as well as the language used to describe them, turn out to be fabrications of the modern scholar and are not part of the original myth.
There are several different versions of ancient myths and only one bible narrative. As believers we maintain that the originals were inspired and without error. As they exist today, they are 99.5% textually correct with only minor copyists errors. None of these errors affect the central/main doctrines.
