Microbes produce spherical sand grains on Mars.

They are not hollow. No aliens in Earth ooids. Martian microbes were in Martian ooids.

Original post has a link to an article. Its Figure 10 marks many nuclei of ooids.

Sorry I didn't see the nuclei of ooids, didn't see the genetic/DNA material

I will have a look again, do you have better evidence?

a reply to: Raggedyman
Nucleus of ooids has nothing to do with DNA.
However, DNA is in modern ooids, because modern ooids contain numerous various organic matter, including various species of cyanobacteria (in different ooids), remains of other organisms.
Ooids are dwellings built by microbes. Microbes lived in ooids. Microbes stored food in ooids. Ooids do contain inorganic matter.

Quote from the third paragraph in phys.org...

"Co-researcher Dr Bob Burne from ANU said the new study found that ooids were made of concentric layers of mineralised microbes, debunking the popular 'snowball theory' that ooids were formed by grains rolling on the seafloor and accumulating layers of sediment."
Note the news story was published in 2018.

So grains rolling on the seafood gain mass, ahem

We disagree, sorry

I said ooids were made by microbes, not by rolling on the sea floors.

We pretty much had this info in ALH84001. Found in 1984 they did not analyze it until 1996.
Just bringing it up outside of that research is problematic for me, because some very important scientists almost had fist fights over it. The way things are today, the new tech will get the credit.

You said it excellently. I also found ooids in meteorite ALH84001. Dr. David McKay did not call them ooids. He called them carbonate globules. They are the same thing. In 1996, no one was sure that microbes made the carbonate globules (ooids). Now new technology shows ooids are made by microbes. So, meteorite ALH84001 did contain ooids, which are signs of past Martian life. Scientists are afraid to take another look at the meteorite, because many TOP scientists are afraid to lose the debates.

A real top scientist has to have an open enough mind to debate it objectively.
Did you actually get to do research on that piece?

I am calling confirmation bias
Pretty good if you want grant moneys

It floats well on a conspiracy site

Concentric layers can be made by annual flooding and mineral deposits in the water attaching to...

whatever, aliens

I wrote an article about ooids found on Mars: www.omicsonline.org...

By the way, I don't like debates, because debates produce bad feelings.

Hear that, but if those you debate are professional, egoless and people concious, the world would be a better place for sure.
That is great about your article! I am downloading the pdf now, but it is taking a long time. Cannot wait to read it, thanks!
