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

Oxygen level - This is one of 3 main factors to explain why the Cambrian event (& Avalon which brought about the ediacara [sponges & jellyfish] ) couldn’t have occurred earlier. Only through billion of years of photosynthetic activity could the earth’s atmosphere and oceans build up sufficient oxygen to support life which transpired in day 4 (biblical Hebrew contains only about 3000 words, consequently, most nouns possess multiple ‘literal definitions’. ‘Day’ has 4 one of which is ‘a long but finite time period’.)

Day 5 - Sea animals & specialized land animals. Explosive speciation. For the first approx. 85% of life’s history on earth, there were no creatures we would refer to as animals. Then suddenly swarms of diverse sea animals emerged with for the first time sporting appendeges, limbs, skeltons, specialized organs, none related to the ediacaras. This sudden appearance is acknowledge as a challenge to the macro-evolutionary model.

You do know that "suddenly" in that context is 10,000,000 years. It is sudden on an evolutionary scale, not a human scale.

Ref: Richard Dawkins, The Blind Watchmaker, http://terebess.hu/keletkultinfo/The_Bli...hmaker.pdf - "For example the Cambrian strata of rocks, vintage about 600 million years, are the oldest ones in which we find most of the major invertebrate groups. And we find many of them already in an advanced state of evolution, the very first time they appear. It is as though they were just planted there, without any evolutionary history".

And you not only dishonestly took that out of context, you stupidly did so when he has said you would.
