I Have Found My Twin Flame

I'm a little confused because there's this girl on instagram that is the same age and has the same star sign as my twin, we haven't really talked yet but we have liked alot of each others pictures, my question is could this be a soulmate? Or could it just be a random coincidence? My other theory is that it could be god answering my prayers because a couple months ago I Prayed for god to send me somone like my twin
