You still have to produce the electricity, and the electric engines and batteries have higher carbon emission when manufactured than the conventional engines
This, at best, is inelegantly stated, and is more likely incorrect on the grounds of making many assumptions, some of which are likely incorrect.
The lifetime carbon footprint of a car is (for simplification's sake):
carbon footprint of making the car + carbon footprint of operating the car, ie:
manufacture + fuel.
What you seem to be arguing (just from the text of your post) is that the carbon footprint of the manufacture of electric cars is greater than that of a gas powered car. This might be true! Giant batteries are in fact difficult/costly in a variety of ways to produce.
However, you might be trying to say some variation of either:
The gap between the footprint of producing two cars is so great that one cannot overcome it with the lifetime difference in footprint between fueling the cars.
There isn't a difference in lifetime footprint of fueling the cars, since producing the electricity itself has at least equal footprint to the production of gas.
Either of these are demonstrably false at least in some scenarios.
For the first, it would rely on an assumption of a certain lifetime, or lifetime fuel consumption as standard across the cars. No matter what the delta of manufacture, if the delta of fuel is nonzero, there's some number that when multiplied by the fuel delta that overcomes.
For the second, it's neither true that cars are as efficient at turning gas into electricity as gas powered power plants (if they were, power plants would likely just be big fields of car engines), nor that there are power plants (see: solar) that have themselves significantly lower footprint than traditional fuel power, and by transitivity, fuel engines in cars.
Anyway, this appears to be a pretty commonly spouted falsehood that is attractive to believe because there are certain parts of it that (like any other good conspiracy theory) make the person who accepts it feel smarter and more in the know of details and facts than those that believe the consensus. Most people don't know that battery manufacturing is environmentally quite bad. How bad? Who knows! Most people don't consider that the electricity comes from power plants that burn fuel. Are they more efficient than car engines? Who knows!
A bit of googling debunks this one pretty thoroughly, though -- if you don't readily accept my debunking above. There's lots of good charts and figures and things like that. Like this one:
If you were just trolling, good job I guess.
