It's a strange concept to grasp, but according to research, about four out of 10 of us invent our first childhood memory. Rather than having experienced something, we could have fabricated a fake memory from videos or photos we've seen. We could have been influenced by a story recounted to us that spurs our minds on to adopt someone else's memory as our own. What it means is that memories of our younger years, especially before the age of two, may be inaccurate, or  entirely false.

But why don't we have clear memories from that age? Well, our ability to retain memories from before the age of two isn't great. While at that age we do have short-term memories, according to Catherine Loveday, an expert in autobiographical memory at the University of Westminster, the memories that infants make are not long-lasting. This is possibly due to the rapid creation of brain cells in our early years. Some scientists also believe that as we get older, our childhood memories fade and after the age of seven, we get some kind of 'childhood amnesia.
 
So why do we create fake memories? Some experts believe that there is a clear desire for a sense of self and having a cohesive story of our existence. Creating memories can fill in the gaps – giving us a more complete structure for our early lives. As we get older, we want to have a complete picture of our entire lives.
 
So, the next time someone says they have a clear memory from when they were one – or even before - just remember that while it could be true, there's a chance they just invented it at some point in their lives.
