So you're saying that colliding particles together in the past didn't result in superhot plasma?
So by that logic gravity never used to exist either and just because we drop a pencil now doesn't mean the pencil will fall to the ground the next time we drop it just because every single time a pencil has been dropped on the Earth in recorded history it has fallen to the ground as a result of gravity. What an enchanted world you live in.
You can't just take the laws of physics and go "meh... doesn't mean it always has worked like that... the laws of physics aren't constant". Either show me some evidence to demonstrate that that stance has even the remotest chance of holding true or hush until you've got something concrete.
