The first question pre-answered: the post title means "Six Questions" written in Bengali. No Bengal tigers were adversely affected during that brief moment of translation.
Q1. Did the souls of "humans" exist on the 5th dimension before it was decided by the miners to create humanoids on Earth? If so, before the creation of humans on earth where were they born or did they even get born in the third dimension?
C: Yes, of course. Souls are permanent, with no beginning or end. There is no time in effect for our souls, no expiration date. Many souls who chose to incarnate as part of the first created humanoids had already passed through the incarnation experience before, some on Earth but on other planets also.
Q2. You say that the instinct to love and protect babies is a genetic trait which was inserted. Are there aliens who don't have this trait?
Q3. Is there is a limit to the life span of humans which was genetically inserted by aliens? What was the reason for choosing such a "short" life span, compared to aliens and why was the infancy and adolescent period extended in humans as compared to other animals?
C: Yes, about a century of Earth travel. Short is a HIGHLY relative term, to the point it is almost meaningless for the purpose of this question. The range of a life's duration was selected to allow for scheduling flexibility of nearly or absolutely certain events, and also random choice (i.e. "free will") leading to effects, results & consequences, all within a framework, design or goal of achieving learning and growth. This related somewhat to life already on Earth; what was the expected lifespan of an equally complex organism? Examples are an orangutan, gorilla, horse, all canines, felines and so forth.
Infancy and adolescence as a typical percentage of the expected human lifespan is about the same as with other complex animal life forms; the difference is mental development in humans versus others.
An example we provide; a horse might live twenty years but is considered well into adulthood at two, thus ten percent. A human reaching adulthood at eighteen to twenty years would have to live almost two centuries, to match this proportion. The answer is, the horse is not as mentally mature as humans typically believe.
Q4. "The Annunaki" - from which part star cluster or galaxy did they come from?
C: The Milky Way, about 15,000 human light years from the opposite edge of the galaxy, almost 180 degrees opposite Earth. About seventy thousand light years away.
Q5. How many years ago did the second DNA upgrade to create Homo Sapiens take place?
C: The DNA upgrades were all performed at approximately three Earth decades after the creation of the first humanoids, when the mining period was considered finished.
Q6. "Thus the home planet masters came to this star cluster ..." ... who were the "home planet masters" and where did they come from?
C: The "Annunaki" civilization sent an expeditionary team; they had masters, leaders, bosses or managers back on their home planet; these were the masters of the explorers set to locate, obtain and return with gold. The masters' representatives came to meet with members of OUR star cluster's alliance or federation, independent of their miner, explorer gold hunter scavengers.
