The cycle process has no start no finish.
We can date the oldest objects being about 14 Billion years. The question is how much time is taken up in a singularity.
Active Black Holes play an important part in the recycle process. As we see with M87 and other large active centres.
The universe did not start with a singularity. It is part of the never ending never process.
No start No end.
