Well, M*W's got a point. Let's just go with it for the sake of argument. While monotheism probably didn't originate with Akenaten, it certainly took on a new meaning. Now, according to the argument, it was this new meaning (application of the Sun Disk to monotheism as a single deity) which influenced Judiasm, and Judeo-Christian religions to follow. Ok. I'll bite.
What is believed now IS NOT what was believed then. Though Judeo-Christian symbolism is imbued with such ancient sun-worship influence, it isn't understood in such a way. This means that there was a shift in thought concerning the whole system of beliefs sometime between then and now. THAT OR, how we understand Egyptian religion is not how Egyptians understood it.
In any case, what we understand to be ancient Egyptian religious beliefs do not coincide with modern-day Judeo-Christian religious beliefs. In fact, they haven't coincided for the past 2000 years. Presumably, Jewish religious beliefs also did not parallel what we believe to be ancient Egyptian religious beleifs for centuries before that.
How are we to account for this? Shall we say, as M*W and others would like, that there is some kind of grand ancient conspiracy to hide the truth of the matter from the masses in some kind of twisted means of controlling the masses? Now, I've heard some conspiracy theories in my time, but that one takes the cake. Rather, and more probably, the truth of the matter resembles something like this:
One of the many nomadic tribes from the area of the Near East first settled in the area of Mesopotamia. Later, either all or part of this group shifted out of Mesopotamia to the west, Abraham (a Semitic name, found on tablets from Mesopotamia, not having Egyptian etymology) being the personage under whom this story was rendered. This group settled first in the southern area of the Levant (as can be attested to in the Archaeological record). These people are a different race than the Canaanites. With them, they brought Mesopotamian religious idea(l)s, including particular gods (such as the main creator god Enlil, later El, as well as Ishtar, later Astarte, and others) Not long afterwards, many of these people shifted south and west into Egypt, and were assimilated into Egyptian culture, but not fully.
It was around this general period that we see the story of Akenaten, and his diversion from Egyptian religious norm in the making of the Aten as the monotheistic god. If we are to say that Akenaten and Moses were the same persons, and that he really was part Hebrew (hapiru), then this may be accounted for in the Bible, as he left Egypt at an early age and found people who revealed his true lineage to him (likely descendants of Abraham who settled in southern Levant, and that general area as I've earlier attested to). This may account for his creation of the egyptian sun disk cult, as he had previously been raised in Egypt, with Egyptian religion, but brought back with him religious idea of monotheism, originating actually from this Hapiru tribe. After his death, this cult died, and there was a large shift of the Hapiru out of Egypt back into the Levant, being unable to be properly absorbed into Egyptian culture (just as was the case in Mesopotamia).
It was around this time that they began to develop a strong sense of cultural identity, and they began to asssert themselves as a cultural group in the Levant. This is also strongly attested to in the archaeological record. Because they began to assert themselves as a cultural group, they needed leadership, and it was about this time that these peoples develop a kingship, and it is during this time that we have strong correspondence in the archaeological record with the OT books of Kings (of the later kings David and Solomon, Hezekiah, etc... but not Saul).
So it is that we find within Jewish religious thought many similarities between Egyptian and Mesopotamian religions. Obviously, if a group of people live in a particular place for any amount of years they pick up on the local cultural identities. This, however, does not mean that these different cultures were the origins of the basic religious thought of that group. So it was with the Hapiru. Furthermore, how those different Mesopotamian and Egyptian gods and goddesses were understood also has extreme significance. Just because you adopt a particular god as an indentifier with your own god, doesn't mean you've adopted everything that is associated with that god in the other culture. Enlil (later El) was the main creator god in Sumer, and so was adopted as an identity of the monotheistic god of the Hapiru for that very reason, but this doesn't mean that they believed in the Sumerian god Enlil, they simply found parallel in Enlil with their own god. Likewise with the Aten, Ra, and so forth. They merely took parallels of these gods with their own. Likely, this is why they were combined into one god, instead taking particular aspects of these gods and combining those aspects to make one that was a closer parallel to their own.
In other words, what they were attempting to do was exactly what the early Christian mission was, that is to take whatever aspects of another religion were true and incorporate it into their own so as to root out the false and combine all religions into a single whole. This is the ideal that Jesus was said to have upheld, and which the Christian Church attained toward (which is why there is just about no part of the Catholic Church that is original, and not based on pagan religious beliefs and rituals), but that the Jews of the time had forgotten.
If you think for a moment that Christianity, or Judaism, having so many parallels with other religions is proof of Christianity's falseness, then you've completely missed the point of Christian thought. And if that isn't the present-day Christian way of thinking, then most Christians have completely missed the point of Christianity. If anything, all of these parallels that you have shown are a strength and testament to the achievement of Judaism and Christianity in their mission.
