Ah Ha!
Ancient alien spaceships caused climate change and brought in the ice age — to their demise.
I used to be a skeptic, but I may be converting. $2 Trillion. If Al can get $1 Trillion ...

Well, if it’s our solar system, dey bees home boys.
Venus was NEVER a greenhouse planet. There is very little free water in its atmosphere, and the average atmospheric temperature is over 900 degrees Fahrenheit, at which point water dissociates, creating free hydrogen, while the oxygen is taken up by various sulfur compounds, and the hydrogen quickly recombines into other substances or escapes to space altogether.
There may be enough of both hydrogen and oxygen to combine into a decent supply of water, once the planet cools enough, but until the heat is radiated off by some means, Venus is forever a stillborn twin of earth. The “cloud cover” is largely sulfuric acid, and most of the atmosphere is carbon dioxide.
You want a REAL “climate change project”? Terraform Venus.
OR perhaps we could just admit that “ in the beginning God.....”
The one word answer to this is “no.”
Our star system is a third or even fourth generation system. The first systems were composed entirely of hydrogen and helium (the helium forming in the fusion of hydrogen). Even today, the universe consists of 99 percent hydrogen and helium.
The heavier atoms (called “metals”) were formed in the burning of “the ash” of dying star systems and in implosions. The burning of the ash results in heavy atoms including iron, carbon and oxygen. It takes supernova to produce yet heavier atoms such as gold and uranium.

Now, think about our planet. In consists mostly of iron, nitrogen, carbon, etc., and has lesser quantities of just about everything else that doesn’t have a short half-life. This means that our star system had to have formed relatively recently, from materials expelled by supernovae. BUT this also means that ANY star system in which life could form had to have formed relatively recently.
IT IS THEREFORE IMPOSSIBLE for intelligent life to come to this star system “billions” of years ago.
If you want to push this thing to the limit, maybe intelligent life could have come here a few hundreds of millions of years ago.
Having said everything I have already said, it must be recognized that the formation of the universe, of stars and of star systems, of our star system in particular, of our planet, of life and of life in all of its wonderful variety involved a series of such improbable events that “miracle” is the only way to describe them. If, therefore, you belief in miracles, you might allow that supernatural creatures might have been here or anywhere or everywhere, from the beginning.
From the “March For Science” crowd.
Time to bring back out the “Men In Black” “memory eraser thingy”!
God’s been there forever. It is presumptuous of us to believe that we and the angels are his only sentient creations.
