Can a horoscope show a person as incarnation of God

[SaSirEkha]

spiritual supremacy and power depends on 12th sublord and smooth progress in spiritual path depends on 11th sublord
so, check 1st, 5th, 11th, 12th sublords and if 3 out of those 4 sublords are connected to 12th house significators, then that person will have high spiritual powers which will remain hidden(sometimes not even known to that person) but will come out when in need.

Also coming to rama, krishna etc, there\'s no historical proof of their existence.
As rama and krishna mantras were described in vedas which were told and spread much ahead of treta yuga and dwapara yuga.
so their mantras and energies are powerful, not themselves as human incarnations

i dont think few rules can seperate horoscopes of gods and demons.
it is said that Ram and Ravan were born in same Rasi.
but their characters and lifestyles were different.
this proves that dividing people into 12 rasis based on birthdates/nakshatras gives vague picture.
every 12th person cannot have same personality and cannot go through same events

i dont know exactly what happens when gods incarnate on earth, but certainly when demons take birth, bad omens can be seen
