First I’ll post a snippet of a larger article. Anyone interested can see the author and link at the bottom:
We may now summarize the weaknesses, nay, hopelessness, of all so-called scientific theories regarding the origin and age of our universe:
(a) These theories have been advanced on the basis of observable data during a relatively short period of time, of only a number of decades, and at any rate not more than a couple of centuries.
(b) On the basis of such a relatively small range of known (though by no means perfectly) data, scientists venture to build theories by the weak method of extrapolation, and from the consequent to the antecedent, extending to many thousands (according to them, to millions and billions) of years!
(c) In advancing such theories, they blithely disregard factors universally admitted by all scientists, namely, that in the initial period of the birth of the universe, conditions of temperature, atmospheric pressure, radioactivity, and a host of other cataclystic factors, were totally different from those existing in the present state of the universe.
(d) The consensus of scientific opinion is that there must have been many radioactive elements in the initial stage which now no longer exist, or exist only in minimal quantities; some of them - elements that cataclystic potency of which is known even in minimal doses.
(e) The formation of the world, if we are to accept these theories, began with a process of colligation (of binding together) of single atoms or the components of the atom and their conglomeration and consolidation, involving totally unknown processes and variables.
In short, of all the weak scientific theories, those which deal with the origin of the cosmos and with its dating are (admittedly by the scientists themselves) the weakest of the weak.
It is small wonder (and this, incidentally, is one of the obvious refutations of these theories) that the various scientific theories concerning the age of the universe not only contradict each other, but some of them are quite incompatible and mutually exclusive, since the maximum date of one theory is less than the minimum date of another.

Thanks. And before sin there was no decay, and when it did we can only speculate the aging that took place at that point. And then there is the “gap” theory.
