"Why till date Science cannot explain that which Force or Energy works behind starting Heartbeats in an Embryo of 21 days to 23 days, any time? " The force is certainly described by quantum electrodynamics, the only major force in all sorts of routine processes. The difficulty is that living systems are extremely complicated, so that understanding cell differentiation, exact timing of developments, and so forth is as hard as for any other biological problem.
"Is start of Heartbeat in an Embryo; is the starting point of a ‘Life’??" Here we can definitely not answer the question, not because it is too hard but because it has no scientific meaning. At what stage of development you choose to apply the word "life" is a question of word choice, not of scientific fact.
"Does a Sperm have intelligence/ sense"? So far as we can tell, they have very little sense.
"how in just 23 Chromosomes it (or say he/she) caries all information"? 23 chromosomes is a very long sequence of nucleotide base-pairs, over 3 billion of them. That can store an enormous amount of information, about 1000 times more than the words in a long novel like War and Peace.
"Why Scientists cannot create BLOOD in laboratory, while have developed nearly all other human organisms in laboratories? " I'm not sure what you mean by that. There are no artifical versions of most organs. Red blood cells can't directly dupicated in cell culture, because they don't have nuclear DNA, so that's perhaps what you mean.
"We all know that all leaving things/organism has Energy & same when dead don’t; " There are no particular changes in energy (in the physics sense of the word) when a living thing dies. If it's warm-blooded, a bit of heat probably gradually flows out to the surriounding materal.
