Upon what basis do you make that claim? Do you allege that the environment now is the same as it was more than 2,000,000,000 years ago? This is horseshit on the order of that stupid attempt you made to advance the young weak sun paradox, which is no paradox at all, because it only works if you assume that the atmosphere billions of years ago was the same as it is today. Do you allege that the oceans billions of years ago were identical to those on the earth today? If you do, upon what basis do you make such an allegation? In fact, if you make that claim, you will be wrong; dead wrong, in fact, from the point of view of life.
Three and half billion years ago, there was almost no free oxygen on the earth. Geological evidence suggests that there may have been as much as 100 times more carbon-dioxide in the atmosphere as there is today. Free oxygen is a poison gas to many forms of life which survive in the present day, and which are descended from the earliest forms of life. Do you not understand just how disastrous the rise of cyanobacteria was for life on earth? Do you not understand that the oceans billions of years ago had almost no free oxygen dissolved in the water, and that what was there was quickly removed by free radicals in the water, such as iron? Do you not understand that the rise of cyanobacteria lead to what can be alleged to be the greatest extinction event in the history of life? Do you not understand that anaerobic organisms only survive today in portions of the ocean floor (such as volcanic vents) which contain little or no free oxygen? Do you not understand that, therefore, it is highly unlikely that any life form exactly like those which existed before free oxygen was common in the oceans and the atmosphere still survives?
Apparently, you don't understand such rather basic things. Apparently, you are so ignorant that you can pose a question which so glaringly demonstrates your ignorance.
Given that you have repeatedly stated that you believe the earth to be on the order of thousands of years old, are you not being fundamentally dishonest to engage in such arguments at all?
