Its funny how people decode the stories of vedas in human form. Vedas are all about science. Everything else in vedas apart from science is just noise.
Daksha and Aditi were not real human beings. Rather Daksha and Aditi are terms (names) referred to elementary particles (like newly discovered Higgs Boson) that are responsible for the process of creation.
It is same as how an elementary particle splits itself into two different particles due to interactions with quantum fields. This explains Aditi sprang from Daksh and Daksh from Aditi. Aditi with her 7 out of 8 children took the process of creation forward. That's the reason why aditi is referred as mother of indra, sun, etc. Hence those 7 children could be rest of the particles that are responsible for creation of this universe like photon, neutron, protons, etc.
Please stop giving human forms to gods. An energy this big cannot exist in a human body because our body cannot handle that amout. Not just krishna and rama are avtar or vishnu but every single particle, matter and antimatter everything is avtar of vishnu. Every animal, every plant, every insect and every human being just like rama and krishna.
(Kan kan me bhagwan hai, kehne ko to pata sabko hai, lekin maanta koi nhi)
Brahma, Vishnu and Mahesha were never real humans rather
Brahma is referred to the collective consciousness,
Vishnu is the space (the ultimate quantum field) that exists everywhere, even in the vaccum (something in nothing) that is constantly wobbling throughout the universe giving birth to particles. This field is the main source of energy.
And Mahesha or Shiva is the Time.
Vishnu and Shiva together are the Space-Time.
And all three together forms the state of nothingness, the quantum state.
