What science calls “Aliens”, religion calls “Angels”

[unitedwestand]

i might be an alien, im probably an alien, they say i was born here? but i was too young to remember, & im too skeptical to just take their word, im probably alien

[leandrocavagnoli]

Certainly a DNA test on the organic material contained in the sphere would be necessary 😮

[alexdimonico]

I always felt that humans were derived from distant planets but I didn't know how it began...this truly does make alot of sense, planting seeds is what got me.
I believe science is almost there on this one👍🏾👌🏾

[JimKermott]

If ancient aliens made your ancestors, who made them?

[philanimanqele]

This is a repeat episode, common now! And ancient astronauts say "YES"

[alw]

If it is just us.. seems like an awful waste of space

[neanderthalsnavel]

The seeding of life from planet to planet via rocks that were sent into space from worlds with life by asteroid and comet hits seems like a very reasonable way for life to spread.

So is it time for me to build an altar to a little metal sphere with primordial ooze coming out of it😂

[ravindrachahar]

They reuploaded this video for some reason. I have already seen this one months ago

[lindagore]

I think everyone should go and watch the orphan trains. That will get you thinking.

[northerners]

So our ancient ancestors are aliens too? 👽

[elizekohler]

I still would like to know where the dinosaurs came from. Why our planet, not elsewhere?

[nicksavage]

NO,
There is transfer of
Micro organisms
Simple cells that over time wont make a human
Building Blocks
Amino Acids etc

[RiddledEnigma]

As I keep saying for the longest time. The earth was a alien dumping ground.

[mrhassell]

Francis Crick wasn't aware of the full story behind the Anunnaki and if he had of been, he would have had the answers why human DNA is the way that it is.

[rokko_lasushe]

If we were seeded, are we seeding the earth like planets??

[riverc]

I’ve always wondered why if these aliens were SO advanced why did they just cut rocks and stacked blocks for early man.

[sergiopardo]

Yes absolutely correct we have been planted here truly believe it
