Where did the universe come from? Atheistic origin science has no answer.

stars have already gone through several cycles, the first ones fused hydrogen and helium to form heavier elements that astrophysics called metals. subsequent stars used these metals to form smaller, and hence longer-lived stars suitable to form rocky planets. the ashes of these smaller generation of stars enriched earth with the chemical form of metals; i.e., iron, nickel, moly, copper, etc. high concentration of these metals are poisonous to advanced life in soluble form. various forms of bacteria over a billion years fed on diluted soluble metal compounds converting these compounds into insoluble forms. the decayed residues of the bacteria yielded the concentrated ores.
so this bacteria activity over a billion years worked on the earth’s environment, made it safe for advanced life and produced ore deposits which without would have assured stone age isolation for homo sapiens sapiens.
