Oh but they (fertilised eggs) are very much like a person in that they possess a diploidnumber of chromosomes whereas gametes (sperm and ova) possess a haploid number. Two full sets of chromosomes vs one full set. A good place for a "beginning".

A good place for us to arbitrarily select as a 'beginning', for some, but not all, purposes.
But not a beginning in any objective sense.
Chromosome number is not one of my go-to tests when encountering an object, in order to decide whether it is a fellow human. There's nothing non-human about human gametes, and they are clearly distinguishable from the gametes of other species. Nobody mistakes a human spermatozoan for a grain of sycamore pollen - which should be a commonplace error if haploid cells were not demonstrably specific to a particular species.
Sorry, but a haploid human cell is still clearly a human cell.
I am not deciding who is human and who/what is a sycamore. I am countering the statement that "nobody has ever been able to see anything even remotely like a person when looking at a fertilised egg?!"
The haploid cells are in search of/awaiting another haploid cell to begin[ dividing by mitosis in order to form a human. This probability is a beginning, not without obstacles and total failures on the way, yet the human race continues. Haploid cells represent dormant possibilities only, and no possibility in humans of successfully completing to form another human without the required other and different human gamete.
A good place to start unless you want to go back all the way to the Big Bang and before that. But we do not know who was banging whom/what then, where, why, and how many times, so I prefer to think that a particular human began as above, even if I don't know who banged whom then, where, why and how many times or if it was artificial insemination that did it.
