The reason they are connected in so many discussions is that they both require an old creation while young earth creationism limits this time to days each day comperable in length to the time between two successive sunsets.Hi All, sorry but it is really a big question mark for me: when people discuss "Evolution" another topic "Big Bang" is being attached to it.
It is entirely two different topics.
Simply saying: the first one deals with living things (Animals and Plants, etc)
the second one is non-living things : (rocks, elements, the moon, the stars, space, energy, light, temperature, etc.
if one have an idea why the two topic is being connected, that will be helpful a bit... because i really cannot find a strong correlation or association of the two.
If young Earth creationism is true, neither Darwinian Evolution nor Big bang can be true as they are described.
