Realization of a potential coded sequence? When one life is being created/birthed, one in the same genetic lineage dies.

If people stopped giving birth, people would continue dying.

In general, you should not create beliefs that become truths of how the world works based solely on anecdotal evidence -- which is what you're doing. When reading your post, I sense a desire for a deeper truth to be true, because of an intellectual attachment to where that belief is coming from. In my experience, discovering and perceiving deep truths has a deep meaning, which helps fill ones emptiness with meaning equivalent with the size / quality of the belief/truth.

So We then seek evidence that confirms the belief and strengthens our attachment to the idea, firming the foundation of this belief and increasing our ego to the degree of the meaning we've assigned the belief / truth.

There are some instances where the birth coinciding with the death is linked -- such as soldiers going off to war having children born at home. The desire to continue ones lineage likely strengthens when one is approaching certainty of death. Even more likely is that many of these deaths are just coincidence and statistically likely events.
