When addressing time as it is known in our universe, there is no stretch in defining a past or the beginning. The rate of expansion and the cosmological constant point definitively to a finite moment. [Creation]
The blueprint or design is fine tuned to a degree that chance is relegated to the impossible. Take the force of gravity. If a ruler represented the possible range for the force of gravity and you extended it from one end of our known universe to the other, by moving the setting 1 inch, you would be unable to have sustainable life or conscious observers.[Humans] Just gravity and the cosmological constant alone make a compelling argument for design. There are at least 18 more parameters needed for human life.
We are rare if not unique, even for our universe.
You need some faith, but a detailed study of the Bible, [especially Isaih the mini Bible], and the laws governing us, can only logically lead to one conclusion. God created us and gave us a personal Savior Jesus Christ.
