Especially when it comes to 'before' the Big Bang. So how can we know if God is necessary or not?
for thousands of years man thought the earth was 6000 years old
then common thought was no its a old earth.
then it was darwin is a nut, now only evolution is taught in schools
evolution of mankind is just nature doing its thing and evolution of planets is the same way, its just nature of the universe.
look at how far we have come with evolution in general, its been a nightmare to deal with religions over known facts
when getting specific about what happened 14 billion years ago in a place we cannot go to and investigate, you cant blame science.
ever since homo sapiens have been on the planet they have always made/imagined religions and gods and spirits for the things we do not know, it has slowed down progress towards the real facts. Its a hurdle man does not need. The first 100 years homo sapiens were on the planet I garantee you that they had some form of spirit or religion or god probably handed down from neaderthal's maybe not.
Therefore their conclusion is not that a God is unnecessary, but that the Christian God is unnecessary
if this were to be true, "IF" it would be because they are the ones that put up the largest fight against them.
I happen to feel science does not look at gods or myths to explain abiogenesis or evolution of the universe becuase the thought again "to me" seem absurd to think nature needs to be created.
Gods would not just blow smoke and have planets appear. we know how they are formed. In the future im sure we will know more about 14 billion years back, we already know a little and what they do know does not include myths in my opinion
