Chondrites are known to have evidence of basic organic compounds required for the beginning of more complex organic life.Where do they originate?Surely they show that some where in the galaxy that life was trying to burst through before we have evidence of life on earth

CF has always been a site that welcomes people from different backgrounds and beliefs to participate in discussion and even debate. That is the nature of its ministry. In view of recent events emotions are running very high. We need to remind people of some basic principles in debating on this site. We need to be civil when we express differences in opinion. No personal attacks. Avoid you, your statements. Don't characterize an entire political party with comparisons to Fascism or Communism or other extreme movements that committed atrocities. CF is not the place for broad brush or blanket statements about groups and political parties. Put the broad brushes and blankets away when you come to CF, better yet, put them in the incinerator. Debate had no place for them. We need to remember that people that commit acts of violence represent themselves or a small extreme faction.

Life doesn't try to burst through, life is nothing more than reactions.
Now, if you'd like to tell me what "organic compounds" are in your book, that might help the discussion. But the most simple organic compound is made by H20 and CO2 to become C6H12O6 which as far as I recall, could probably be done though autoionization.

yes sugars are important part inthe origin of life but they have been identified in the pre cambian when there was no evidence on earth

Ok... but you didn't tell me what you considered 'organic compounds'. Are we talking about amino acids, proteins... what?

Yes smple amino acids had been found back as 1950 along with carboxylic acids but the important part was the find of sugars,sugar alcohols,smaller amountsof dihydoacetone,glycerol and the evidenceof of polyels.There are several articles in"nature" but Ican't giv the exact dates

This does not parse very well. No evidence on earth for what? Sugar? If that is what you are saying than you are clearly wrong. Since there are Precambrian fossils there must have been sugars since life requires sugars.

Yes it was a poor reply.Imeant the early pre cambrian from 4.5 to 3.8 billion years when there were a large number of impacts on the earth and no traces of fossil life on earth
