Science is not a religion. It is dishonest to claim that it is.
As for origins? Beats me.
Here are five hypothesis regarding the origin of the first life forms.
b) Aliens from another planet and/or dimension travelled to this planet and -- deliberately or accidentally -- seeded the planet with the first life forms.
c) In the future, humans will develop a means to travel back in time. They will use this technology to plant the first life forms in Earth's past, making the existence of life a causality loop.
d) A divine agent of unspecified nature zap-poofed the first life forms into existence.
e) Any method other than the four described above led to the existence of the first life forms.
How does life come into being from inert materials? where did the inert materials originate?
Science is indeed a religion. It requires much more faith than I can muster!
