The word “kind” is in reference to Genesis 1, biogenesis by kind of creature. Those Scriptural passages are supported by the possibility for multiple episodes of abiogenesis or biogenesis. IOW, if life is not a continuum then there is no dispute there. On the other point, time is geometric. That is a major point of both special relativity and general relativity. In the vicinity of a black hole, while a week passes, 40 years may pass on earth. While a space ship travels at 1 earth’s gravity velocity for 25.3 years – 5x1010 years elapse on earth. And due to the inflationary model, at the inception space/time coordinates of this universe, while 6 equivalent earth days pass – approximately 15 billion years elapse on earth. That is due to the inflationary model:
In case you want to know, this exponential rate of expansion has a specific number averaged at 10 to the 12th power. That is in fact the temperature of quark confinement, when matter freezes out of the energy: 10.9 times 10 to the 12th power Kelvin degrees divided by (or the ratio to) the temperature of the universe today, 2.73 degrees. That's the initial ratio which changes exponentially as the universe expands. - Age of the Universe
