Your question is a bit on the far-fetched side, but an interesting one in the least. I would love to field it!
...starting all over like our ancesters did and for them we are preparing a capsule to teach them what we have learned and accomplished. The question is: Do we also put in the ideology of god into that capsule?? The information of all the major religions we have created?
Given the moral codes in religions, and the symbolism used in their writings, I'm of the opinion that the religions were started as a means of preventing a primative peoples from killing themselves and each other. Maybe not the first set of laws, but one that the authors intended to be the most effective.
Or maybe they were the first means of creating an order among the masses in early civilizations. In that case, they were, at the least, an incredibly creative way of keeping the peace.
But then, you have to look at the fact that there are many different religions, in which case you have to wonder just how effective these strict set of laws actually were, if the detractors to them could simply break free and create his own. Granted, I would imagine the detractor wouldn't have it that easy, but still, his ideals garnered supporters, and lived on.
Now, assuming that there was some cataclysm that severely cut human population, and for a time there was a detachment from civilization, and that humanity would again rise into dominance, you ask if religion should be left for them. Now, you say this capsule would teach them all we have learned and accomplished, but you do not clarify in what manner the relgion would be taught. i.e. are you saying we would teach religion as if it were truth, or do you mean the people would learn of the religions in the same way we learn of Greek and Roman gods today?
If you are saying the capsule would teach religion to the people as a way of keeping them in order, then I say no. The people in this civilization would make their own religions, and hopefully do a better job of it this time around.
To teach them of religion objectively, and tell them what it's logical purposes were, then yes, I can see doing that.
It's hard to say what they would do with our knowledge. If what science believes now is true, then we may have taken basic events in nature (Lightning, rain, visible heavenly bodies) and made religions of them. I cannot imagine what we would have done given a starting point; a capsule--to suit this discussion--of technologies and language and culture, from what these people could only deduce was out of nowhere. Would they not, in turn, take the capsule as a gift from God? Would they not tell stories of the great and powerful gods that sent them this gift of knowledge? Would they not, therefore, attribute everything they accomplish from that point forward to the God or Gods that gave them their jumpstart?
See, the concept of an all-powerful being is one from a primative, uneducated mind. All creation stories smack of authors who had the wrong idea concerning thier enviroment. They did not know that the water that fell from the sky was rain, and it came from clouds, not some vast ocean in the air. They didn't know that the large rock they were on rotated, and considered day and night to be seperate entities, rather than attributing it to the direction their side of the planet was facing. They had not yet built the tools to witness evolution, nor had the capacity to consider it.
The way these beliefs were twisted into ways to hold the primitive people accountable for their actions should have been phazed out as we became intelligent enough to create our own set of laws and rules, removed from the ancient and no longer useful idea of spiritual punishment. And, in time, they most likely will.
Anyway, my point is that I would imagine the new civilization would create thier own religoin no matter what, considering that we have so many different religions, so why not let the new people come up with what they will. There is no reason to leave them with the baggage that we have.
My vote: Mention it in historical terms, but don't pass it off as being true.
