If you go by the existence of human life according to evolutionists, which right now is 2 million (and constantly changing), it would be about 150 million per year.
Accepting that number to solve for X, how many mutations per year would get us to 30 Trillion if we only had 150 million years to work with? I'd go from the start of life altogether, not just humans; it isn't going help much, I believe, even if we start talking about billions.
x = 30 trillion / (Select age life began) In billions, or some other number
Solve for X insert when life began to see how many successful mutations towards human life would be required from that time forward each year during the period selected.
About 8000.
Keep this in mind: that is how many mutations there are from the beginning of life for one human life, not a male and female, just one human. Then there are all the other human lives, and each of them has its own cell makeup. Looking at it this way removes the deep time out of the argument when you have to account for the work through time for ALL LIFE today. We see the length of time, and we can look at the human species and see that number for each human. Nothing about this can be dismissed or ignored due to time, even using billions of years.
We couch our discussions about creation and evolution in terms of deep or very short time. Both groups say what they believe can account for all that we see today in how they define how things work and why. Suppose you are an old-universe Theist or Atheist evolutionist. In that case, deep time can answer all the complex issues surrounding life, while a young universe Creationist says God did it, so it means all the complex issues are done due to his design.
For questions unanswered, it is either God of the gaps or evolution of the gaps, which can be a blanket comment on the unknown. Neither statement helps move the needle; it only irritates the side directed at.
I looked it up and saw that the human body has about 30 trillion cells, about 200 different types. This is a huge number of cells, and if you are a common ancestor evolutionist, you need to account for each one due to mutations.
For a thought exercise, I'd like to know how many mutations it would take to reach the 30 trillion cells in the human body today. I have done the math already, but I think it would be better if you did it yourself. It would be more meaningful. Every mutation is considered good, and all move towards life; a best-case scenario for getting the job done is what it looks like practically per year.
This exercise assumes abiogenesis occurred, evolution from a common ancestor is true, and every mutation correctly leads to human life, so there is no justification for age, abiogenesis, or evolutionary mutations. They are all accepted as true, and we only want to know how many per year from the starting point of life per year and how many mutations it takes to reach 30 trillion. I've asked these other places, and people have either ignored it or come up with issues like cancer, longevity, and so on, but today they never actually touched the question.
This is simply a find X, the number of mutations per year to reach 30 trillion. If we know 30 trillion is the goal, we need to know the start date to determine how many years are needed to find X.
