There’s a clickbait headline making the rounds this morning in regards to statements made by Helen Sharman and the idea that aliens definitely exist. Sharman traveled into space back in 1991 and the fact that she is making the statement would seem to lend it credence. To some degree it’s a misleading headline in that Sharman is not saying she knows aliens definitely exist, that the government has been hiding it, and she has evidence from her trip to Mir.
What Sharman is saying is the likelihood aliens definitely exist is extremely high. That there are so many stars, so many planets, that the chemistry of the earth is so similar to those places, the odds of life not being anywhere else in the universe is exceedingly small. She even goes so far as to speculate that perhaps aliens are already on earth but we cannot detect them.
Sharman is almost completely correct in everything she says. The number of planets and the physical makeup of life which corresponds directly to the most abundant elements in the universe, make it extremely likely that life does exist elsewhere. I think it’s very likely we are less than decades away from finding such life on the various moons of the solar system and even on planets like Mars or Venus.
Where Sharman goes wrong, and where she defies the scientific method, is when she states aliens definitely exist. We have no evidence of such. Certainly, it seems very likely that aliens exist. I argue that it’s all but impossible alien life does not exist. The universe is simply far too vast for there not to be aliens. There was life, there is life, there will be life. However, I have absolutely no definitive evidence to indicate there is life, nor does anyone else.
I do not think that Sharman is trying to start or validate nonsensical alien theories. I think her statements are made with honest intent. The reason this is a story at all is because she is an astronaut, well, technically a cosmonaut as she was aboard the Russian space station Mir. This fact make it seem as if she is saying something she is not, the human mind leaps to conclusions that are not actually articulated.
What many people unfortunately think when they read the headline, and even the story itself, is that Sharman is confirming some nefarious plot in which she met aliens while a cosmonaut and is now spilling the secrets. This is not the case and it was not her intent in making the statement, or so I believe at least.
What she is saying is that, to her, it seems impossible there is not life somewhere in this vast universe. That such life might be on earth right now. I don’t disagree but I also will not say aliens definitely exist for the simple reason that I have no direct evidence of that existence. Until I do, I’ll temper my statements.
In any case, I think the story is an excellent illustration of how we often read more into a statement than is actually there. We want words to mean one thing even when they don’t and we convince ourselves otherwise. Try to avoid this trap.
