Reason is guilding star of my life.

If we use reason and logic ,unbiased with our faith and free from teleology and refer knowlege(from Decades of scientific inquiry and careful research)
It appears nature is always existed,
some phenomena (might be brane collision) results in big bang the energy generated form lighter particles which then results in electron,proton,neutons and then hydrogen atom which in star furnase forms sulphur,nitrogen,carbon etc planets form then life form and life evolves to organism with senses and complex mind(including conciousness) .

This unconcious nature unpurposely Evolves and form product like us -The concious beings which seek purpose.

our mind then creates fantacies(God,after death life-soul,Heaven/Hell,creatures like angels,magick including rituals,astrology,miracles and alternate medicine).
here we say fantacies because these have no proff or evidences they are just based on faith.

Some may assume Human as apex of evolution yet in reality corporal being is merely a disposable vehicle for the reproduction of genetic material,not the other way around.

After death our body,mind and conciousness all dies,We each only get one life,its painfully obvious to most,but its reality.

Any religious scriptures when sceptically analysed it is found that there is nothing devine in them all are man made only.

Phenomenas which are consider as paranormal proff like NDE,Ghosts,out of body experinces,reincarnation memories,ESP,miracles like John of God or alternate medicine(based on chi or Vital Force)when viewed from Skeptical Point has scientific explanation and mostly are psychological phenominas.there is nothing paranormal in it.

In summary,By Critically thinking we get
1)Life has no existance before we born and will not exist after we die.
i.e. we exist only for some finite time
2)There is nothing like supernatural or paranormal like God,soul,angels,Miracle,Heaven.
